aboutTool

File Hash Calculator calculates file checksums to verify data integrity. Use algorithms like MD5 or SHA-256 to ensure downloaded files haven't been tampered with or corrupted during transfer.

howToUse

  1. Drag and drop or select the file you want to check
  2. Toggle the desired hash algorithms (MD5, SHA-256, etc.)
  3. Compare the generated checksum with the one provided by the original source

features

  • Full support for MD5, SHA-1, SHA-256, and SHA-512
  • High-speed hashing for large files
  • Simultaneous calculation of multiple hash types
  • 100% private local processing (no uploads)
  • Integrity checks for any file extension
  • Easy checksum copying

faq

Is my file uploaded?

No, all hashing is done locally in your browser; your sensitive files NEVER leave your machine.

What if the hashes don't match?

This indicates the file is corrupted or has been altered; you should re-download it from a trusted source.
