Redact PDF
Draw boxes over anything sensitive — the page is rebuilt underneath them, so the covered content is gone, not just hidden.
How Redact PDF works
Draw boxes over anything sensitive — the page is rebuilt underneath them, so the covered content is gone, not just hidden.
- Draw redaction boxes directly on the page preview
- The page is rebuilt — hidden text is truly gone
- Undo a box any time before applying

Frequently asked questions
Is the text actually removed, or just covered up?
Removed. Each marked page is re-rendered as an image with the redaction boxes painted in before rebuilding, so there is no text layer left underneath to select, search or copy.
Can I undo a redaction box before applying it?
Yes — click any black box on the page preview to remove it before you run the tool.
Is Redact PDF free?
Yes, and there is no sign-up, watermark or daily limit — everything runs in your browser rather than on a metered server.
