File Hash and Checksum Generator

File Hash and Checksum Generator

Generate SHA hashes or CRC32 checksums for local files.

Choose files for hashing

Hash or checksum Expected value (optional, one file)

Files are read locally. SHA-256/384/512 use the browser's Web Crypto API and require HTTPS or another secure context. SHA-1 and CRC32 are supplied for compatibility checks only, not for security verification. Hashing confirms matching bytes, not that a file is trustworthy.
