About PII redactor
Pattern-based redaction of emails, phones, SSNs, cards, and IPs in pasted text — helpful, not a compliance guarantee.
Before you paste a log into a ticket or a screenshot thread, you often want emails and card-shaped numbers gone. This redactor runs common patterns and replaces hits with placeholders, with counts so you can see what fired. It is a seatbelt, not an ISO certification.
Regex is not a privacy program. Names, free-text addresses, and novel ID formats will slip through. Always read the output. Do not treat a green count as legal clearance for GDPR, HIPAA, or your company’s DPA.
Encryptor is for locking a whole blob with a passphrase. Zero-width cleaner removes invisible characters. Extractors find contacts; this one tries to hide them.
How to use PII redactor
- 1Paste the text that may contain sensitive patterns.
- 2Review redacted output and per-pattern hit counts.
- 3Copy only after a human pass confirms nothing sensitive remains.
What it won't do
- Not a compliance certification or DLP product.
- Human review required every time.
Common questions
Is this PII redactor GDPR or HIPAA complete?
No. Patterns only. Regulated data handling needs process, training, and often purpose-built tooling — not a webpage regex.
What patterns are covered?
Common shapes for emails, phones, SSNs, payment-card-like numbers, and IP addresses. Expect misses and occasional false positives.
Does redaction happen on a server?
No. Text stays in the browser. That still does not make the output automatically safe to publish.
