Paste text or drop any file and instantly compute its MD5, SHA-1, SHA-256, SHA-384, or SHA-512 hash. Need to verify a download or confirm two files are identical? The Validate tab computes the hash and compares it against an expected value in one step — paste the checksum from the download page, drop your file, and get an instant match or no-match result. Algorithm is auto-detected from the hash length so you don’t need to know which one was used. Everything runs locally in your browser. Your text and files are never uploaded to any server.
No ads. No fees. No signup. Just a tool that works.
