Hex Dump / Byte Viewer
Shows the raw bytes of any file as a classic hex dump — offset, hex bytes, and their printable ASCII equivalent. Works on any file, recognized format or not; the fallback for whatever this site doesn’t have a dedicated tool for yet.

When you'd use this
- Looking at a file's actual bytes when no dedicated tool exists for its format yet
- Checking a format's magic-byte header to identify what a file really is
- Investigating an unfamiliar or corrupted file at the byte level
Shows up to the first 64KB of a file — enough to identify a format's magic bytes and header structure without the page slowing down on a very large file.
