Checksum · free, in your browser

Verify a download with its checksum

Software sites publish a hash next to the download. Compare it with the file you got to be sure it arrived complete and unchanged.

Check a file

How to do it

1. Drop the downloaded file on the page.
2. Pick the algorithm the publisher used in Algorithm (SHA-256 for most).
3. Paste the published hash into Expected hash.
4. Read the result: Match means the file is the one that was published; No match means it differs.

Your files stay on this device: Checksum runs in your browser, with no upload, no account and no watermark.

Questions

Does it matter if the hash has capitals or spaces?

No. Spaces, letter case and a prefix such as "sha256:" are ignored before the hashes are compared.

What if the length differs?

Then the published hash is for another algorithm. The page says so; pick the algorithm with the same length.

What should I do on No match?

Download the file again from the official site. If it still differs, do not open it and contact the publisher.
