Best PII redaction software in 2026
PII redaction software strips personally identifiable information, things like Social Security numbers, card numbers, emails, phone numbers, and addresses, out of documents before they're shared. The good tools detect it accurately, remove it for good, and don't put the sensitive document at more risk while doing it.
PII covers names, SSNs and national IDs, card and account numbers, dates of birth, emails, phone numbers, and addresses. Rules like GDPR and HIPAA treat most of it as protected.
The checks that matter
Detection has to catch SSNs, card numbers (validated by checksum), emails, and phone numbers, and you need a review step to confirm before anything is removed. The removal has to be permanent, meaning the PII is deleted rather than hidden behind a box that can be lifted, and metadata has to go too, since PII hides in the document properties as well as on the page. A black box that can be removed isn't protection, and a tool that uploads a PII-heavy document is its own risk. How covered text gets recovered.

How we handle PII
Manual redaction is free and runs entirely in your browser. A paid plan adds one-click PII auto-redact that finds and boxes SSNs, card numbers, emails, and phone numbers for you to review, then burns the redaction in. See the PII redaction page.
