Hash Tools

Compute MD5, SHA-1/256, CRC32, and more. Use the universal hash generator or batch all hashes at once. Keccak256 available for Ethereum workflows.

What you can do

  • Generate a single hash with the algorithm you need
  • Compare MD5, SHA-2, and CRC outputs side by side with All Hashes
  • Use Keccak256 for Ethereum and Solidity tooling

All tools run locally in your browser. No account required.
