Redact PDF – Black Out Sensitive Info

Select a PDF, draw black boxes to hide any private content, and export a flattened redacted PDF. Everything happens in your browser—nothing is uploaded.

⚠️ Warning: Redactions are permanently burned into the page images and the original text is destroyed—hidden information is not recoverable from the output.
This is secure for most use cases, but not a certified legal/compliant redaction method. For sensitive legal, medical, or compliance documents, use a professional redaction tool.

Your PDF will open in a new tab. Tap Share (📤) and choose Save to Files to save it to your device.

FAQ

Does this really hide the original text?
Yes, the original PDF text/content is destroyed and unrecoverable by normal means.

Can I undo a black box?
Yes! Use Undo on each page. Clear erases all redactions for that page.

Is this legal for sensitive/government docs?
For most users, yes, but it is not certified legal/compliant. See the warning above.

Can I redact multiple pages at once?
You'll need to redact each page individually by drawing boxes on each one, but you can download all pages together as a single redacted PDF.

Does this work offline?
Once the page loads, yes! Everything runs in your browser, so you can redact PDFs even without an internet connection.

Will this work on large PDF files?
Yes, but very large files (50+ MB) may take longer to process and use more memory. For best performance, consider splitting very large documents first.
