What is File Hash Calculator?
A file hash calculator computes cryptographic digests (SHA-256, SHA-384, SHA-512) for any file using the Web Crypto API. Perfect for verifying downloads, comparing file versions, or generating integrity hashes. All processing happens on your device.
How to use
- Upload one or more files by dragging or clicking the file picker.
- Choose which hash algorithms to compute (SHA-256, SHA-384, SHA-512).
- Copy individual hashes or download a full report with all computed values.
Result
Upload a software installer and compute its SHA-512 hash, then compare it against the publisher's posted hash to confirm authenticity.
