Frequently asked questions
General
Do you store or see anything I type into the builder?
No. Every generator runs as JavaScript in your own browser. Nothing is sent to a server, there's no account, and no analytics record what you type. Your answers are saved only to your browser's local storage, so they're still there if you close the tab and come back.
Where do I upload the finished files?
Almost all of them belong in the root directory of your website, alongside your homepage — for example example.com/robots.txt. security.txt is the one exception: publish it at /.well-known/security.txt, and optionally also at /security.txt for convenience.
Do I need all 16 files?
No. robots.txt and manifest.json cover the vast majority of practical need. Treat the rest as optional extras: llms.txt, security.txt and ads.txt are worth adding if they apply to you, and the more speculative files are low-cost, low-certainty additions for sites that want to be thorough.
What's the difference between an established, emerging and speculative file?
established means a formal standard or a long-settled convention with real enforcement, like robots.txt or ads.txt. emerging means an active proposal gaining ground but not yet universally supported, like llms.txt or ai.txt. speculative means no governing spec exists at all — a convention a few tools have started using, with no crawler documented to require it.
Will adding these files improve my Google ranking?
Not directly. robots.txt affects whether pages are crawled at all, which matters for indexing, but the AI-facing files here are aimed at large language models and AI answer engines, not classic search ranking. Treat them as part of a wider AI-visibility strategy, not an SEO ranking shortcut.
Does llms.txt guarantee ChatGPT or Claude will cite my site?
No. It's a genuine, actively maintained specification, but independent audits have found no measurable link between having one and being cited more often by AI answer engines, and some major search providers have said they don't use it. Publish it as good practice and a clear content map, not as a guaranteed result.
I already have a robots.txt. Will the builder overwrite my existing rules?
The builder only ever generates a new file for you to download — it can't see or edit anything already on your server. Compare the generated file against your existing one before you upload it, so you don't lose rules you already rely on.
What's included now?
Around 140 tools across four areas: AI & SEO site files (all 16 common files, from robots.txt to llms.txt), structured data (7 schema.org types), image tools (photo metadata, tag editors, format converters, QR codes, and a full set of photo-editing tools), and file tools spanning Office documents, PDFs, archives, developer formats, security credentials, and forensic artifacts from Windows and macOS. Every tool runs entirely in your browser. Browse the full tool guide for the complete, current list.
Structured Data
What does the Structured Data section actually give me?
A ready-to-paste JSON-LD snippet for whichever schema.org type applies to a page — Organization, LocalBusiness, Article, Product, FAQPage, BreadcrumbList or Person. Copy it into the <head> of the relevant page; it's what search engines read to build rich results.
Image Tools
Does the QR/Barcode Reader upload my image anywhere?
No. Decoding happens entirely in your browser using the open-source ZXing library, loaded from a CDN — the image itself is never uploaded or sent anywhere.
Will the GPS remover or metadata remover reduce my photo's quality?
No. Both tools only touch the metadata segments of the JPEG file — the actual pixel data is never re-encoded or recompressed, so image quality is unaffected.
What's the difference between the metadata remover and the C2PA remover?
The metadata remover strips everything — EXIF, XMP and IPTC — indiscriminately. The C2PA remover is targeted: it only removes C2PA Content Credentials manifests and known AI-generation XMP signals, leaving other metadata like your camera details or copyright line untouched.
Can the MP3 tools handle album artwork?
Not yet. The viewer, editor and remover all work with the common text frames (title, artist, album, year, genre, comment) and the legacy ID3v1 tag. Embedded album art is a separate frame type that isn't currently read, written, or preserved when you save changes.
How reliable is the hidden-data finder?
It's genuinely best-effort. It checks for two common, simple techniques — data appended after an image's end marker, and a straightforward sequential least-significant-bit encoding. Encrypted or more sophisticated steganography won't be caught, and a "not found" result never proves a file is clean.
Why do some Image Tools show a "speculative" badge?
The same honesty system used for the AI Site Files applies across the whole toolkit. XMP AI-generation signals and the hidden-data finder rely on conventions or heuristics with no governing standard — useful, but not guaranteed. C2PA is further along (an active industry spec) but still marked "emerging" since support isn't yet universal.
Does editing or removing FLAC tags re-encode the audio?
No. Both tools only rebuild the metadata block section at the start of the file — the audio stream itself is copied byte-for-byte, unchanged. This was verified directly: files produced by both tools pass the reference FLAC encoder's own integrity check.
Why doesn't the WAV/BWF Viewer show any broadcast metadata for my file?
Not every WAV file has a "bext" chunk — it's a broadcast-industry extension (Broadcast Wave Format) common in professional audio and radio/TV production tools, not in everyday WAV exports from consumer software. The viewer shows the file's regular audio properties either way.
Does the M3U/M3U8 Viewer play the media in the playlist?
No, it only lists the entries — title, duration, and file/URL for each one. It also recognises basic HLS streaming tags, so it can read a segment or variant playlist as well as a simple local one, but it doesn't fetch or play any of the referenced media.
Does the Subtitle Viewer show styled text, like bold or italic cues?
No, inline formatting tags such as <b> or <i> are stripped for display. You get the plain cue text and its timing, not a styled preview of how the subtitles would look over video.
Does the MP4/MOV Inspector play or preview the video?
No. It reads only the file's "moov" metadata box — track types, codecs, durations, and dimensions — without loading or decoding any actual video or audio sample data. That's also why it stays fast even on very large video files.
Can the HEIC/HEIF/AVIF Viewer show me a preview of the actual photo?
No, it reads the container's metadata boxes only — brand, dimensions, item count — without decoding the actual HEVC or AV1 image data. That's deliberate: it means the tool works even in browsers that can't display HEIC or AVIF images natively.
Does the Background Remover upload my photo anywhere?
No. It uses a real machine-learning segmentation model that runs entirely in your browser via WebAssembly. The model file itself (not your photo) is downloaded from a CDN the first time you use the tool and cached by your browser afterwards — your image is never sent anywhere.
File Tools: Everyday Formats
Can the JWT Decoder verify any token's signature?
Only HMAC-signed tokens (HS256, HS384, HS512) — paste the secret and it checks the signature locally in your browser. Tokens signed with RSA or elliptic-curve algorithms (RS256, ES256, etc.) are decoded so you can read the header and payload, but their signatures aren't verified; the tool says so plainly rather than showing a false pass or fail.
Is it safe to paste a real JWT or secret into the JWT Decoder?
Nothing you paste is sent anywhere — decoding and signature verification both happen locally in your browser using the Web Crypto API, the same "nothing leaves your browser" promise that applies to every tool on this site. That said, treat any token or secret with the same care you would anywhere else.
Does the .eml viewer let email HTML run scripts or track me?
No. The HTML body of an email is rendered inside a sandboxed frame with scripts disabled and no access to the rest of the page, specifically to prevent anything embedded in the email — tracking pixels included — from running or phoning home automatically.
How are iCalendar recurrence rules decoded into plain English?
The iCalendar Viewer reads the RRULE's frequency, interval, days, month, count and until fields and builds a sentence from them, e.g. "Every 2 weeks on Tuesday and Thursday, until 2025-12-31." Common patterns are covered well; unusually complex or custom rules fall back to showing the raw rule text instead of guessing.
Does the MBOX Viewer ever mistake a message's own text for a new message?
No — it only treats a "From " line as a new message boundary when it appears at the very start of a line. A line inside a message body that happens to start with "From " is conventionally escaped by mail clients as ">From ", which the viewer correctly leaves alone as ordinary body text.
Does the Gzip / tar.gz Explorer extract files to disk?
No. It decompresses the file in memory, entirely in your browser, to show you the original filename, metadata, and — for a tar.gz archive — the list of files inside with their sizes. Nothing is written to disk or uploaded anywhere.
File Tools: Document & Design Tools
Does editing a PDF's metadata change the original file?
No. The PDF Metadata tool downloads a new, edited copy of the file — your original upload is never modified or sent anywhere. Only the document-info fields (title, author, subject, keywords) are changed; page content is untouched.
Why doesn't the Font Viewer show metadata for WOFF2 files?
WOFF2 compresses its internal tables with Brotli, a more involved compression scheme than the zlib used by WOFF, so this tool doesn't decode WOFF2 metadata. The live glyph preview still works for WOFF2 files, though — that part is rendered directly by your browser, which decodes WOFF2 natively regardless of what this tool's own parser supports.
Can the PSD Viewer show me the actual Photoshop image?
Only if Photoshop saved an embedded thumbnail preview with the file, which is common but not guaranteed. The tool reads layer names, document info, and that thumbnail directly — it doesn't composite or render the full layered image itself, which would need much more of Photoshop's rendering logic than a lightweight browser tool can reasonably reproduce.
What .sketch file versions does the Sketch Viewer support?
The modern, JSON-based .sketch format used since Sketch 43 (the format Sketch has used for years). It reads page, artboard and layer-type structure — it doesn't render the actual design, only its structure.
Do the Word and Excel viewers work with the older .doc/.xls formats?
The main Word and Excel metadata viewers only read the modern .docx and .xlsx formats, which are zip archives with an internal XML structure the tool reads directly — the older binary .doc/.xls formats use a completely different structure. For those older files, use the Legacy .doc/.xls Metadata Viewer instead, which reads that older structure directly.
Does the PDF to PNG Image Export tool upload my document anywhere?
No. Every page is rendered directly in your browser using the same PDF engine (pdf.js) used elsewhere on this site — the PDF never leaves your device, and neither do the exported images until you choose to download them.
What does "only the CSS your document actually uses" mean in the Markdown to HTML Converter?
Each template is a full stylesheet covering headings, tables, images, code blocks, and more. If your document doesn't contain a table, for example, the exported file won't include any table styling at all — it's tested against your actual rendered content and only the rules that match something real are kept, so you never ship unused CSS.
File Tools: Word Document Tools
Does the Style & Font Inspector show fonts and styles that aren't actually used?
No — it reads fonts from each run's actual formatting and styles from each paragraph's real style reference. A font sitting in the document's bundled font table but never applied to any text won't appear.
Does the Table Extractor preserve cell formatting in its CSV export?
No, only the text content. Merged cells are read as repeated or empty cells depending on how the document itself stores them, since a CSV has no concept of a merged cell.
Can the Comments & Replies Extractor always show reply threading?
Only when the document includes a commentsExtended.xml part recording those relationships. Older documents, or comments made in some Word versions, may not record threading even though the comments themselves are still fully readable.
Will the Track Changes Viewer show changes that have already been accepted or rejected?
No. Once a tracked change is accepted or rejected in Word, the underlying tracking data is removed from the file entirely — there's nothing left for this tool (or Word itself) to show. It only reads changes that are still actively tracked in the saved file.
Is the Legacy .doc/.xls Metadata Viewer reading the same kind of data as the modern .docx/.xlsx viewers?
The properties themselves are similar (title, author, dates, and so on), but the underlying structure is completely different — a "Property Set" inside a Compound File Binary container, the same container format used by .msg files and Windows' Thumbs.db, rather than the XML files inside a modern .docx/.xlsx zip archive.
Can the Embedded Object Extractor download the objects it finds?
It currently lists every media file and embedded object with its size and, where an embedded object is itself a legacy-format document, that document's own properties. Direct download support for each item may follow.
Does the Word to Markdown Converter handle tables and images?
No — it converts headings, bold/italic text, and bullet/numbered lists, since those map cleanly to Markdown syntax. Tables aren't converted; use the Table Extractor instead, which is built specifically for pulling table data out cleanly.
Does the Redaction Tool actually remove the text, or just cover it up visually?
It genuinely rewrites the document's underlying text — this is the whole point of the tool, since a visual cover (a black box or highlight) is the most common way real-world document redactions fail, letting the "hidden" text be copied out or recovered. It searches across run boundaries too, so a match split mid-word (which Word does constantly, e.g. for spell-check styling) is still found completely, and the same search also covers text still present in tracked-change insertions or deletions — not just the currently visible document.
File Tools: Excel Document Tools
Does the Hidden Sheets/Rows/Columns Finder catch "very hidden" sheets?
Yes. Excel has two levels of sheet hiding — an ordinary hidden sheet a user can reveal from the Unhide menu, and a "very hidden" sheet that only VBA code can unhide. Both are flagged the same way by this tool, since both represent data a casual viewer wouldn't otherwise see.
Does the External Link Finder open or fetch the linked workbook?
No. It only reads what's already stored inside the workbook you dropped — the target file path and which of its sheets are referenced — without contacting that file or any network location at all.
Does the Formula Extractor show what a formula actually calculates to?
No — it shows the formula text itself (and flags it if it uses a volatile or cross-workbook function), not the computed result. Use the Sheet to CSV/JSON Converter if you want a formula cell's last-calculated value instead.
Why does a formula cell sometimes export blank in the Sheet to CSV/JSON Converter?
It exports each formula cell's last-calculated cached value, which Excel stores alongside the formula itself. If the workbook was saved by a tool that writes the formula but never actually calculates it, that cached value can be empty — the CSV/JSON export will be blank for that cell even though the formula itself is present.
Does a flag from the VBA Macro Extractor & Risk Scanner mean a macro is definitely malicious?
No — it's a starting point for review, not a verdict. Plenty of legitimate macros use Shell, Auto_Open, or similar patterns for entirely ordinary reasons. The scanner surfaces what's actually there so you can judge it in context, the same spirit as this site's .env secret scanner.
How does the VBA scanner find macro source code inside the workbook?
VBA module source is stored compressed, preceded by a variable-length uncompressed prefix. Rather than fully parsing the VBA project's internal directory structure to find each module's exact offset, this uses a pragmatic offset-scanning heuristic — also used by some real-world tools — that tries decompressing from every plausible position and keeps the result that looks like genuine source code. In rare cases, an unusually laid-out project could be missed.
File Tools: PDF Advanced Tools
Does the PDF Text Extractor work on scanned documents?
No — it reads the PDF's existing text layer, which a scanned or image-only PDF doesn't have. Use the OCR tool under Image Tools instead, which reads text directly out of the image.
What does "not embedded" mean in the Font & Resource Inspector?
The font's outline data isn't included in the PDF file itself — the PDF just references it by name (e.g. "Helvetica"). That's completely normal for the standard 14 base fonts every PDF reader supports, but for anything less common, "not embedded" means the document could display differently, or fall back to a substitute font, on a device that doesn't have that exact font installed.
Can the Bookmark / Outline Viewer edit or reorder bookmarks?
Not currently — it's a read-only viewer for now.
Why would a PDF have layers I can't see any option to toggle?
Optional content groups (layers) are mostly used by CAD and design tools, and toggling them requires a PDF reader with layer support in its UI — many simple viewers just render whatever's visible by default and don't expose a way to turn layers on or off at all.
Does the Embedded File Extractor download the exact original attachment?
Yes — the file data is decompressed directly from the PDF's internal structure, so what you download is byte-for-byte identical to whatever file was originally attached.
Does the JavaScript Extractor & Risk Scanner run the scripts it finds?
No — never. It only reads and displays the script source code; nothing embedded in the PDF is ever executed.
Can Page Tools apply a reorder, rotation, and deletion all in one go?
Not in a single step — each operation produces its own downloaded file. To combine changes, run the tool again on the result of the previous one, feeding each output back in as the next input.
Does the PDF Redaction Tool actually remove the text, or just cover it up visually?
It genuinely rewrites the page's underlying drawing instructions — this is the whole point of the tool, since a visual cover (a black box or highlight) is the most common way real-world PDF redactions fail, letting the "hidden" text be copied out or recovered. The result was checked against two independent PDF engines (pdf.js and poppler's pdftotext) to confirm the redacted text is genuinely gone from the file, not just hidden underneath something.
Does the PDF Redaction Tool work on every PDF?
It reliably finds and removes text in the very common case of ordinary Latin-text fonts with a standard encoding. It doesn't currently decode custom-encoded or CID/Type0 fonts (the kind often used for embedded CJK text), so matching text set in one of those may not be found.
File Tools: AI Model Inspector
Does the AI Model Inspector download or process the full model weights?
No — it reads only the header/metadata section of the file (the part describing tensor names, shapes and data types), not the tensor data itself, which is normally the vast majority of a model file's size. This keeps it fast even on large model files, and nothing is uploaded anywhere either way.
Why doesn't the AI Model Inspector list ONNX operator nodes?
ONNX files are Protobuf-encoded, and this tool deliberately reads only the top-level model metadata and the graph's declared input/output names — not the full list of internal operator nodes. That keeps the tool fast and simple for the most common question ("what is this model, and what does it expect as input/output") without needing to render a full graph visualization.
File Tools: Package Inspectors
Does the APK/IPA Manifest Viewer install or run the app?
No — it only reads the app's declared manifest (AndroidManifest.xml, decoded directly from its compiled binary XML format) or Info.plist. Nothing is installed, executed, or sent anywhere; this shows you what the app declares it can access before you decide whether to install it.
Does flagging an npm install script mean the package is malicious?
No. Lifecycle scripts like postinstall are extremely common and usually completely benign — many packages use them to compile native addons or run setup steps. The npm Tarball Inspector flags these scripts so you can see what's there before installing, not to render a verdict.
Does the .crx viewer verify the extension's signature?
No — it reads the manifest.json inside the extension's zip payload, but doesn't verify the cryptographic signature Chrome itself checks. It answers "what does this extension want to access", not "is this signature valid".
File Tools: Developer & Data Formats
Is it safe to upload a real pcap or access log file, since they can contain sensitive traffic?
Yes — the same "nothing leaves your browser" promise applies to every tool on this site, pcap and log files included. That said, these files genuinely can contain real IP addresses, URLs, and traffic patterns, so treat them with the same care you would anywhere else; the site simply never uploads or transmits what you drop into it.
Does the SQL Dump Viewer run any of the SQL in the dump?
No. It only reads the text of CREATE TABLE statements to extract table and column names — no SQL is ever executed, and no database is involved. This is different from the SQLite Database Browser, which does run real queries against an in-memory database.
Does the SQLite Database Browser write changes back to my file?
No. It loads an in-memory copy of your file using a real SQLite engine (compiled to WebAssembly), and any query you run — including ones that change data — only affects that in-memory copy. Your original file on disk is never modified, and nothing is uploaded anywhere.
Why are some headers hidden by default in the HAR File Viewer?
HAR exports from browser DevTools often contain real session data — Authorization tokens, cookies — in plain text. Headers like Authorization, Cookie and Set-Cookie are redacted by default so you don't accidentally expose them (for example, while sharing a screenshot); a "Show sensitive headers" button reveals them when you actually need to see them.
Does the Git Object Inspector work with a whole .git folder, or a full repository?
It reads one loose object file at a time — the individual files git stores under .git/objects/xx/ for each blob, tree, or commit. It doesn't read a whole repository at once, and it doesn't cover packfiles (.pack/.idx), which is how git stores objects once it has compacted a repository's history.
File Tools: Security & Credentials
Is it safe to paste a private SSH or GPG key into this site?
The same "nothing leaves your browser" promise applies here as everywhere else on the site, and these two tools go further still: they deliberately never read the actual secret key material at all, encrypted or not. An OpenSSH private key file always stores its corresponding public key in cleartext alongside the private section, and an OpenPGP secret key packet always begins with the same public-key fields a public key packet has — so the algorithm, bit length and fingerprint are available from that cleartext portion alone, without this tool ever needing to parse, decrypt, or display the private material itself.
Does the SVG Sanitizer guarantee an SVG is completely safe afterward?
No tool can offer an absolute guarantee, but this one is built to fail safe: it works from a strict allowlist of elements and attributes, removing anything not explicitly permitted, rather than trying to blocklist specific dangerous patterns. Scripts, event handlers, javascript: URIs and external references are always stripped. If something you needed got removed, it means that element or attribute wasn't judged safe enough to include by default — not that the sanitizer missed it.
Does the X.509/CSR viewer verify that a certificate is trustworthy?
No. It decodes the certificate's ASN.1/DER structure directly and shows you what it says — subject, issuer, validity dates, public key, SANs — but it doesn't verify the signature or check the certificate against any trust store. "Valid" in this tool's summary means "within its stated validity dates," not "trusted by a browser or operating system."
File Tools: Disk & Virtualization
Does the ISO9660 Disk Lister mount or open the disk image?
No. It reads the ISO9660 filesystem structure (including Joliet and Rock Ridge extensions for long filenames) directly from the file bytes to build a file/folder listing — the image is never mounted, and no files are extracted.
Does the VHD/VHDX Inspector or the OVA/OVF Viewer read the actual disk contents?
No, for both tools. The VHD/VHDX Inspector reads only the header and metadata regions of a virtual disk file — never the disk block data itself — which is why it works instantly regardless of how large the virtual disk is. The OVA/OVF Viewer reads only the OVF XML descriptor inside the archive; embedded disk images (.vmdk/.vhd files) are listed by name and size only, never opened or extracted.
File Tools: Geo, Fitness & Everyday
Does the .msg Viewer send my email or attachments anywhere?
No. It reads the Compound File Binary container and its MAPI property streams entirely in your browser. Attachment data only leaves your browser if you click Download on a specific attachment — nothing is uploaded automatically.
Does the FIT File Parser support every field a fitness device can record?
No, by design. It covers the common fields — activity type, duration, distance, GPS points, and heart rate — rather than the full FIT protocol. Developer fields (custom, device-specific data) are safely skipped so they don't corrupt the rest of the file's parsing, but their values aren't extracted.
Is the GPX/KML Viewer's map preview a real map?
No. It's a simple offline projection of the track's shape, scaled to fit the points in the file — no map tiles are fetched from any server, which is why it works fully offline, but it isn't a geographic basemap you could use for navigation.
File Tools: Color Profiles
Does the ICC Profile Viewer's gamut chart work for CMYK printer profiles?
Not usually. The gamut chart plots a profile's declared rXYZ/gXYZ/bXYZ colorant primaries, which are typically only present in RGB display profiles. CMYK/printer profiles generally don't include these tags, so only the tone-curve and metadata sections will show data for those.
File Tools: Windows & Binary Format Tools
Does the PE Import Table Viewer or Section Viewer run or execute the file?
No, for either tool. Both read declared structures directly from the file's bytes — the import table and the section table — without loading, executing, or disassembling any of the actual code.
Why doesn't the PE Version Info Viewer show anything for my file?
A version resource (VS_VERSIONINFO) is optional in the PE format. Most commercially built Windows software includes one, but many command-line tools, small utilities, and files built without an embedded manifest don't — that's an accurate "no version info found," not a bug.
Does the Windows Shortcut Viewer's target path always show the real target?
When a shortcut stores a LinkInfo local base path, yes — that's read directly. Otherwise the target is reconstructed from the shell item ID list, which is a best-effort read rather than a fully-typed parse of every possible shell item variant, since Windows uses many different item types for different kinds of targets.
Can the Recycle Bin $I Viewer recover my deleted file?
No. The $I file is only metadata — the original path, size, and deletion time. The actual deleted file's content is stored separately in a matching $R file, which this tool doesn't read.
Does the Thumbs.db Viewer show every thumbnail as a clean, viewable image?
Filenames and sizes are read reliably from the Catalog stream. Some older Windows thumbnail formats wrap the actual image data with extra header bytes before the real JPEG/PNG content begins, so a downloaded thumbnail from an older-format file may need that header stripped before it opens cleanly in an image viewer.
How does the Prefetch Viewer handle Windows 10/11's compressed Prefetch files?
It decompresses them fully in your browser first, using an implementation of Microsoft's Xpress Huffman algorithm (the same compression Windows itself uses to wrap these files in a "MAM" container) — nothing is uploaded anywhere to decompress it, and the file never leaves your machine.
Does the EVTX Viewer show every field from every event type?
It reliably extracts the common fields present in almost every Windows event — provider, event ID, level, time, computer, and similar System-section details — by decoding each event's underlying template and substitution values generically, rather than hard-coding specific event types. Highly custom EventData fields specific to one provider's events may not all be surfaced.
File Tools: macOS Forensics
Is .DS_Store related to Thumbs.db?
Only in purpose, not in format. Both are per-folder metadata files an operating system creates automatically without being asked — Thumbs.db for cached thumbnails on Windows, .DS_Store for Finder view settings and icon positions on macOS — but they use completely unrelated container formats under the hood.
File Tools: Comparison Tools
How does the File Diff / Compare Tool decide between a text diff and a binary diff?
It tries to decode both files as strict UTF-8 text. If both succeed, it runs a real line-by-line Myers diff (the same algorithm behind most command-line diff tools). If either file fails to decode as valid UTF-8 — as most binary formats will — it falls back to a byte-level comparison instead, showing which byte ranges actually differ.
General Utilities
Which hash algorithm should I use to verify a download?
Any of the four work for confirming a file wasn't corrupted in transit. SHA-256 is the strongest choice if the publisher offers it; MD5 and SHA-1 are no longer considered cryptographically secure against a determined attacker trying to forge a matching file, but remain perfectly fine for catching ordinary corruption.
Why would I use the Hex Dump/Byte Viewer instead of a format-specific tool?
It's the fallback for anything this site doesn't have a dedicated parser for yet — or for looking at a file's raw magic bytes and header structure directly, which a format-specific tool usually hides behind a friendlier summary.
Does the Base64 tool handle emoji and non-English text correctly?
Yes — text is decoded as UTF-8, so encoding and then decoding emoji, accented characters, or non-Latin scripts round-trips back to the exact original text.
When should I use a data URI instead of a regular image file?
For small, one-off images — an icon or a small illustration — where avoiding a separate HTTP request is worth it. A data URI bloats whatever HTML or CSS it's embedded in and can't be cached separately by the browser, so it's a poor fit for photos or any image reused across multiple pages.
Will a WiFi or contact-card QR code actually work when scanned?
Yes — they follow the same standard conventions (the WIFI: and vCard formats) that phone cameras already recognize, so scanning one offers to join the network or add the contact directly, the same as a QR code generated by any other standard tool.
Image Tools: Photo Editing
How reliable is the Screenshot Cropper's automatic detection?
It's a helpful starting guess, not a guarantee. It looks for solid, low-variation color near each edge — the way a taskbar or title bar is normally drawn — so it works well on typical desktop screenshots but can be thrown off by a dark or patterned desktop background, an unusual window theme, or a screenshot with no obvious chrome at all. The suggested box is always adjustable before you crop.
Does automatic face detection in the Blur/Pixelate tool always find every face?
No — treat it as a starting point, not a guarantee. It can miss faces at unusual angles, partly out of frame, or in low light, and it needs to download a small detection model the first time you use it, so it may take a moment or not be available at all without an internet connection. You can always add, adjust, or remove boxes by hand, whether or not detection finds anything.
Is a blurred or pixelated area genuinely removed, or just covered up?
It's genuinely applied to the image itself, not drawn as a removable layer on top — once you download the result, the original detail underneath the blur or pixelation is gone from the file.
Does the Batch Watermark Generator process every photo the same way?
Yes — whatever text, logo, position, and metadata options you set are applied identically across every photo in the batch, so you only need to set them up once.
Can I load a photo into the Icon Drawer instead of starting from a blank grid?
Yes — uploading an image fits it onto whatever grid size you've currently selected, so it's worth picking your final size first. A detailed photo will look blocky at small grid sizes, which is simply how pixel art works.
