Redact PDF
Black out sensitive content — permanently and unrecoverably.

Files never leave your device
Drag boxes over anything that must not be seen — names, account numbers, addresses — and download a copy where that content is permanently gone. Unlike tools that just draw a black rectangle over live text (which anyone can copy-paste underneath), this tool rebuilds each page as an image, so the text underneath the box no longer exists in the file.
Redaction is the one PDF operation where a mistake becomes a headline. That's why it runs entirely in your browser — the unredacted original is never uploaded anywhere.

Frequently asked questions
Is the redacted text really unrecoverable?
Yes. Pages are re-rendered as images with the black boxes baked into the pixels, and the original text layer is discarded entirely. There is nothing under the box to recover.
Why does my redacted PDF have no selectable text?
That's the trade-off that makes redaction safe: pages become images. If you need the rest of the document searchable, run the redacted file through the OCR tool afterwards.
Is my unredacted document uploaded?
No. Your file is processed entirely in your browser using JavaScript — it is never uploaded to a server, so nothing can be stored, leaked, or read by anyone else.
How is this different from drawing a black box in an editor?
A drawn box just sits on top — the text underneath can still be selected, copied, or extracted. True redaction removes the content itself, which is what this tool does.
