About Text Redactor
Automatically detect and redact sensitive information including emails, phone numbers, SSNs, credit card numbers, and IP addresses.
How It Works
Uses regular expressions to detect common PII patterns in your text, then replaces them with configurable redaction markers. All processing happens in your browser — no data is ever sent to a server.
Step by Step
- 1 Paste text containing sensitive information
- 2 Select which PII types to redact
- 3 Optionally customize the replacement text
- 4 Click Redact to process
- 5 Copy the redacted text
Tips
- Review results carefully — regex detection may miss unusual formats
- Use custom replacement text like [CLIENT_EMAIL] for clarity
- Redact before sharing logs, support tickets, or documents
- Combine with manual review for maximum safety
