File Checksum Verifier

Get SHA-256, SHA-1 and SHA-512 of any file locally and compare with the published checksum. Runs entirely in your browser, nothing is stored.

How this works

The file is read in 8 MB chunks and hashed on your device (SHA-256, SHA-1 and SHA-512), so even very large downloads work without filling memory.

What we never see

The file or its contents. Nothing is uploaded; there is no size limit beyond your device.
