Redact PDF
Permanently black out sensitive information from your PDF — true redaction, not just a visual overlay. Free, instant, and completely private. No other free tool does this properly.
True Redaction — Private & Secure
Redaction happens entirely in your browser using pdf-lib. Black rectangles are permanently burned into the PDF — the underlying content cannot be recovered. Your file never leaves your device.
Easy Draw-to-Redact
Simply draw rectangles over any content you want to hide. Select and delete mistakes, navigate between pages, and apply all redactions at once when you're ready.
