Is auto-redaction permanent?

Yes on matched pages — those pages are rasterized so blacked-out text is destroyed, not just covered. Always review before sharing.

Can non-PII get redacted?

Sometimes. Invoice numbers can look like cards; version strings can look like IPs. Toggle pattern types off before you run.

Does auto-redact upload my PDF?

No. Detection and redaction run in your browser. You can download a privacy receipt afterward.

About this tool

Detect common PII patterns (emails, phones, SSNs, cards) across split text runs, then permanently black them out on matched pages. Joining text items helps catch patterns split across glyphs.

This is pattern-based — not a guarantee of every secret. Always review before sharing. Matched pages are rasterized; untouched pages stay as-is.
