Text Redact
Replace PII patterns in text — emails, phones, SSNs, credit cards (Luhn-validated), IPs, URLs, UUIDs, AWS access keys. Optional custom regex patterns.
About Text Redact
Text Redact finds and replaces personally identifiable information in plain text: emails, phone numbers, SSNs, Luhn-validated credit card numbers, IP addresses, URLs, UUIDs, and AWS access keys, with room to add your own regex patterns. It edits the output text rather than placing visual covers on PDF pages. Everything happens in your browser, so the sensitive data you're scrubbing never gets uploaded.

Frequently asked questions
What PII patterns does it detect out of the box?
Emails, phone numbers, SSNs, credit cards (Luhn-validated), IP addresses, URLs, UUIDs, and AWS access keys.
Can I add my own patterns?
Yes. You can supply custom regular expressions to catch organization-specific identifiers the built-in patterns don't cover.
Is my text uploaded?
No. Redaction runs entirely client-side in your browser, so the text and the PII in it never leave your device.
How is this different from Redact PDF?
Text Redact replaces matching patterns in the output plain text. Redact PDF only adds visual cover rectangles: underlying PDF content may remain recoverable, including after compression. It is not a secure document-redaction equivalent.
Will pattern-based redaction catch everything?
It catches well-structured PII like emails and card numbers reliably, but free-form mentions (a name in a sentence) need a language-aware tool; for that, see Redact PII.
