MD5 File Hash Calculator

Calculate MD5 hash checksums for your files. Verify file integrity with MD5 hashes.

About MD5 File Hashing

MD5 file hashing generates a unique 32-character hexadecimal checksum for any file. This hash can be used to verify file integrity and detect changes.

Key features:

  • Fixed output length (32 characters)
  • Works with any file type
  • Fast computation
  • Client-side processing
  • 100MB file size limit

Security Note:

MD5 is not cryptographically secure and should not be used for security purposes. For security-critical applications, use SHA-256 or other modern hash functions.

Common Uses
  • Verifying file downloads
  • Checking file integrity
  • Detecting file changes
  • Software distribution
  • Data verification

How to verify files:

  1. Calculate hash of your original file
  2. Share both the file and its MD5 hash
  3. Recipients calculate hash of received file
  4. Compare hashes to verify integrity
