What is Redact PDF?
Redact a PDF online free, without uploading it. Draw a box over anything sensitive — it's deleted, not just covered — processed locally in your browser. It runs entirely in your browser, so there's no upload, no server involved, and no account required.

How to Use Redact PDF
- 1.Upload the PDF you need to redact.
- 2.Drag a box over anything to remove — a name, an account number, a signature. Draw as many boxes as you need, across any page.
- 3.Click Redact & download.
- 4.Any page with a redaction box is rebuilt from a rendered image with the box baked in, so what's underneath is truly gone — not hidden text a copy-paste could still reveal. Untouched pages keep their original quality.
Frequently Asked Questions
Is this real redaction, or does it just draw a black box over the text?
Real removal. A page with a redaction box is rendered to an image with the box baked into the pixels before that page is rebuilt — the covered text or image is gone from the file, not sitting underneath a shape someone could delete or copy through.
Does this affect pages that don't have a redaction box?
No — only pages with at least one box are rebuilt from an image. Every other page is copied exactly as it was, keeping its original quality and selectable text.
What's the trade-off on a page that does get redacted?
That specific page loses selectable/searchable text, since it's now an image — the standard trade-off any tool makes to guarantee the covered content is actually gone rather than just hidden.
