This free file hash generator calculates MD5, SHA1, SHA256, and SHA512 checksums directly in your browser. No file is ever uploaded to a server — all processing happens client-side using the Web Crypto API. Use it to verify downloaded files, check file integrity after transfers, or generate checksums for distribution.
