Enter text or drop a file to compute hashes.

SHA algorithms use your browser's native Web Crypto implementation; MD5 and CRC32 run a local implementation. SHA-256 is the standard choice for modern use — MD5 is included for legacy verification only.

Private by design

This tool runs 100% inside your own browser using local JavaScript — your input never touches a server. That makes it instant, offline-capable in many cases, and private even for sensitive data.
