File Hash Comparison Tool
Check whether a selected file has the same SHA-256 digest as a value you trust. The file is read and hashed in your browser.
Files up to 100 MiB are supported. Processing happens locally in this browser.
Your file is not uploaded. A matching digest is evidence that the file bytes match the expected value; it does not prove who published the file or that it is safe.

Digest equality checks byte identity only. It does not authenticate a publisher, establish provenance, or scan the file for malware.
