Questions

How do I verify a download?

Drop the file, then paste the checksum from the download page (or the contents of a SHA256SUMS file). A green tick means the file is intact.

Can I compare two files?

Yes — drop exactly two files and you will see whether they are byte-for-byte identical.

Is anything uploaded?

No. Hashes are computed with Web Crypto in your browser.
