How do I redact information in a PDF?

Upload your PDF, draw redaction marks over the content to remove, click Apply Redaction, and download the permanently redacted file.

Is redaction permanent?

Yes. Redaction permanently removes the content from the PDF data. It cannot be reversed or recovered.

Can someone see text under the black bar?

No. Unlike visual overlays, true redaction removes the underlying data so it cannot be extracted.

What information should I redact?

Personal names, ID numbers, bank details, medical information, addresses, and any sensitive personal data.

Can I redact images and signatures?

Yes. Draw redaction boxes over any area including images, signatures, or handwritten content.

Yes. PDF redaction is completely free with no account required.
