## Answer

Run Auto-redact below to find common PII patterns and black them out permanently on matched pages. Always review the result and run the privacy checker before sharing.

## Limits

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

## FAQ

### 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.
