File Hash Calculator

Calculate MD5/SHA hashes for any file

Select Hash Algorithms

💡 Tips:

  • Algorithm Selection: SHA-256 for general use, SHA-512 for high security, MD5 for speed only
  • File Integrity: Use hashes to verify downloaded files haven't been corrupted or tampered with
  • Duplicate Detection: Compare file hashes to find duplicate files in your system
  • Version Control: Track file changes by comparing hashes over time
  • Security Auditing: Verify file authenticity and detect potential malware
  • Backup Validation: Ensure backup files are identical to originals
  • Performance Timing: Monitor calculation times - larger files take longer to process
  • Copy Individual Hashes: Click copy buttons to use specific hash values for verification
  • Privacy First: All hash calculations happen locally in your browser - your files stay private
