How to redact a PDF safely

A safe redaction workflow does two things well: it removes the sensitive content, and it forces you to verify the exact file you are about to send. If either step gets skipped, mistakes happen.

Start with the visible risk

  • Identify every name, number, address, or block of text that should not leave the file.
  • Check rotated pages, scans, and page edges carefully — those are easy places to miss something.
  • Assume review matters just as much as the redaction step itself.

How to do it

  1. Open Redact and draw boxes over every area that needs to be removed.
  2. Export the redacted file as a burn-in copy.
  3. Open the downloaded PDF in a separate viewer and try selecting or copying near the redactions.

What to do next

  • If hidden metadata also matters, run Sanitize on the redacted output.
  • Rename the file if the original filename itself reveals something sensitive.
  • Keep the original and the cleaned copy separate so you do not mix them up later.
