Anonymize Text

The tool can detect and redact: (1) Email addresses in standard format (user@example.com). (2) Phone numbers in various formats including international. (3) URLs and web links (http/https). (4) IP addresses (IPv4 format). (5) Card-like numbers (16-digit sequences). (6) Full names (basic capitalized word pairs). Each type can be toggled independently.

The tool uses pattern matching (regular expressions) to identify sensitive information types. When found, each item is replaced with a descriptive placeholder like [EMAIL_REDACTED], [PHONE_REDACTED], etc. The tool tracks what was redacted and provides detailed statistics by type.

Use when: (1) Sharing examples or bug reports publicly. (2) Posting logs or error messages on forums. (3) Preparing training datasets without exposing real user data. (4) GDPR/CCPA compliance - redacting PII before sharing. (5) Security incident reports requiring anonymized data. (6) Demo/documentation creation.

Yes! The tool helps achieve GDPR compliance by removing personally identifiable information (PII) before sharing data publicly. All processing is client-side (in your browser), so we never see or store your sensitive data. However, you should review the output to ensure all PII is properly redacted.

Yes! Enable 'Batch Mode' to process each line independently. Perfect for anonymizing multiple log entries, error messages, or records line-by-line while preserving the structure.

Redacted items are replaced with descriptive placeholders: [EMAIL_REDACTED] for emails, [PHONE_REDACTED] for phones, [URL_REDACTED] for links, [IP_REDACTED] for IPs, [NUMBER_REDACTED] for card numbers, and [NAME_REDACTED] for names. This makes it clear what type of data was removed.

Yes! Click 'Upload' to load .txt, .md, .csv, or .log files. The tool will scan and redact sensitive information across the entire file. You can then download the anonymized version for safe sharing or storage.

Name redaction is basic and detects capitalized word pairs (e.g., 'John Doe'). It won't redact names at sentence starts or after punctuation to avoid false positives. For production use, consider reviewing the output manually or using dedicated PII detection services for higher accuracy.

Comparison mode shows your original (sensitive) text and anonymized text side-by-side. The original appears in red highlighting the sensitive nature, while the anonymized version appears in green showing it's safe. Perfect for reviewing what was redacted before sharing.
