What is PII Masker?
PII Masker automatically detects and redacts personal information — email addresses, phone numbers, credit card numbers, SSNs, and IP addresses — from any text using regex pattern matching. Paste in logs, support tickets, or documents and get a safe-to-share version instantly. Both full masking (asterisks) and partial masking modes are available.

FAQ
Is my input text stored anywhere?
No. Regex pattern matching runs as JavaScript in your browser. Text data is not transmitted to any server, and is cleared from memory when you leave the page.
What types of personal information are detected?
Email addresses, phone numbers (US/international formats), credit card numbers, SSN (Social Security Number), and IP addresses (IPv4).
What is the difference between full mask and partial mask?
Full mask replaces all characters with asterisks. Partial mask keeps some characters visible (e.g., last 4 digits of a credit card) to maintain data identifiability while masking.
Are there false positives or missed detections?
Since detection uses regex pattern matching, non-standard formats may not be detected. We recommend reviewing the highlighted detections manually before sharing sensitive documents.
How can I detect only specific types?
Use the checkboxes in the "Detection Targets" section to toggle individual PII types on or off.
