Log Anonymizer

Log File Anonymizer

Replace sensitive data in log files with placeholders to protect privacy and comply with regulations. Anonymize emails, IPs, UUIDs, credit cards, Social Security Numbers, phone numbers, and custom data patterns automatically. Unlike basic text replacement tools, our anonymizer uses intelligent pattern matching to identify sensitive data across different formats, supports custom regex patterns for project-specific data types, and offers multiple replacement strategies (placeholder, hash, or mask) to balance privacy protection with log readability. Perfect for developers sharing logs for debugging, compliance teams preparing logs for audits, and organizations protecting user privacy. Our tool helps you meet GDPR, HIPAA, and other privacy regulations by removing personally identifiable information (PII) from logs before sharing, archiving, or using in documentation. Whether you're anonymizing application logs, server logs, or database logs, our tool provides comprehensive sensitive data detection and replacement that goes beyond simple find-and-replace, ensuring your logs are safe to share while maintaining their structure and usefulness for debugging and analysis.
