PDF Redaction Tool

Finds every occurrence of a word or phrase in a PDF and removes it directly from the page's underlying drawing instructions — genuinely deleting the text, rather than drawing a black box over it (the single most common way real-world PDF redactions fail).

Why it exists

Actually removing sensitive text from a PDF before sharing it, rather than covering it with a black box a determined reader can strip away.

How to use it

Drop a PDF, type the word or phrase to redact, choose case sensitivity, then download the redacted copy.

Good to know

Text decoding is correct for the very common case of ordinary Latin-text fonts with a standard encoding; it doesn't currently decode custom-encoded or CID/Type0 (embedded CJK-style) fonts, so text in those may not be found.
