Redact PDF

Genuinely hides part of a PDF. It does not draw a rectangle over the words — those would stay in the file and come back with a copy-paste: the page is redrawn from scratch, and there is nothing left to recover underneath the black. The document never leaves your device.

Your file stays on your device: nothing is uploaded

How it works

The pages you touch are drawn as an image at the resolution you choose, the rectangles black out the pixels, and the page is rebuilt from that image: on that page no text exists any more, not even the text that stays visible. The other pages are left as they are — vector, light, with text still selectable. At the end the tool reopens the file it just produced and checks two things: that no extractable text is left on the redacted pages, and that the word you searched for no longer appears anywhere. If either check fails, the file is not handed to you and we say so: we prefer an error to a document that looks redacted without being redacted. What this tool does not do, and is better known upfront: it does not touch document metadata (author, title — use “Remove PDF metadata” for those), it does not find text inside a scan, because there is no text there to find, and it does not decide by itself what is sensitive.

Your files are never uploaded. Anywhere.

Not to a server of ours, not to a third party, never. When you pick a file it stays in your browser’s memory: it is read, processed and written back on your device, and you save the result yourself. There is no path that takes it elsewhere, because there is no server to send it to.

  • Processed locallyFormats are handled by WebAssembly code running in your browser, not by a remote service.
  • Nothing to upload, nothing to wait forOther services send your file to a server and then send it back to you. Here the file never leaves: there is no upload to wait for.

  • No files to deleteOthers promise to erase your files after an hour. We have nothing to erase: they never reached us.
