Calculate file hashes and check them against an expected checksum.
Use the guide alongside the working tool.
Open File Checksum Verifier →Worked example
Changing one byte changes the digest; compare a SHA-256 checksum with a trusted publisher’s value.Calculate file hashes and check them against an expected checksum.
Prepare your input
Open a file up to 50 MB and choose a SHA algorithm.
Paste an expected checksum if you want to verify a match.
Review and export
Copy the digest or download a checksum manifest.
Changing one byte changes the digest; compare a SHA-256 checksum with a trusted publisher’s value.
Scope and privacy
Checksums verify byte equality, not publisher identity or malware safety. SHA-1 is offered only for legacy comparisons.
