Real Redaction, Not a Black Box
Sharing a document with sensitive data means the data has to be gone, not hidden. Painting a black rectangle leaves the text recoverable in the file; this tool removes the underlying content entirely.
Unmarked pages keep their original vector quality, so the redacted document stays crisp, searchable, and professional.

Frequently asked questions
What is the difference between redacting and covering text?
Covering text with a black box is cosmetic — the text underneath can still be extracted from the file. Redaction removes the underlying content so it cannot be recovered.
What kinds of content can I redact?
Any text or image you can see on the page. Drag a box over names, addresses, account numbers, signatures, or photos.
Is my redacted document truly safe to share?
Marked pages are re-rendered without the removed content and re-embedded, so the underlying data is gone from the file. Pages you did not mark keep their original quality.
Do I need to register to redact PDFs?
No. Redaction runs entirely in your browser — there is no account and no upload.
