Limits worth knowing

  • Only common patterns — names and unusual formats may be missed.
  • Not a substitute for manual Redact on every sensitive region.
  • Matched pages become images.

Frequently asked questions

  • Is auto-redact permanent?
    Yes on matched pages — they are rebuilt so covered text is removed, not just drawn over.
  • Does auto-redact upload my file?
    No. Detection and redaction run locally.
  • Should I still check afterward?
    Yes. Use the PDF privacy checker for text under boxes, metadata, and attachments.
