About File Hash Calculator
Drop in files and get their checksums — SHA-256, SHA-1, SHA-384, SHA-512, and MD5 (as a legacy checksum, not a security hash) — computed entirely in your browser, up to 200 MB per file, without uploading a single byte. Compare the result against a vendor's published checksum to verify a download, or use it to deduplicate files. Multiple algorithms are computed side by side.
