PII Placeholder Anonymizer
Automatically detect and replace personally identifiable information (PII) with placeholder tokens.
About the PII Placeholder Anonymizer
Mask common email, URL, phone, SSN, card-number and IPv4-shaped text using configurable patterns. This is a pattern-based redaction aid, not a guarantee of anonymity: it does not identify names, verify card checksums or validate every phone or IP address. Review the output before sharing sensitive documents.
Features
- Selectable pattern categories
