File Hash Calculator

File Hash Calculator

Calculate MD5, SHA-1, SHA-256, SHA-512, and SHA-3 checksums for any file — entirely in your browser. Verify file integrity by comparing hashes, process multiple files in batch mode, and handle files up to 2GB with chunked streaming.

Comment utiliser

Drag and drop a file (or click to browse), select which hash algorithms to calculate, and get results instantly. To verify a download, paste the expected hash and the tool will show a checkmark or cross. Use batch mode to hash multiple files at once.
