Why Use This PII Redactor?

Five pattern detectors with toggles: email, international phone, Luhn-checked credit cards, US SSNs, and IPv4 addresses.
Redact mode ([REDACTED-TYPE] labels) and Mask mode (partial preservation like j***@example.com) with per-type match counts.
Custom keyword list for project names and internal codenames, matched case-insensitively.
One-click copy and .txt download of redacted output; .txt file loading via dropzone.
100% client-side processing: pasted text never leaves the browser, which is itself the privacy property.

Frequently Asked Questions

How do I redact PII from text online?
Yes. Paste the text into the tool, choose Redact or Mask mode, and review the per-type match counts before copying or downloading the clean version. Nothing is uploaded at any point.
What is the difference between redact and mask?
Redact replaces a match with a label like [REDACTED-EMAIL]; mask preserves part of it, e.g. j***@example.com. Use redact for logs and datasets, mask when reviewers need partial context.
Does this tool make my data GDPR or HIPAA compliant?
It assists GDPR minimisation/erasure and HIPAA Safe Harbor de-identification workflows by removing pattern-based identifiers locally, but it does not certify compliance and cannot detect personal names. Review matches before sharing.
