Questions

Can it crack a forgotten password?

No. It removes protection you can already open. Forgotten passwords need the original creator.

Are the file and password uploaded?

No. qpdf runs fully in your browser — check DevTools → Network while unlocking.

What is an edit-only lock?

A PDF locked against editing often opens with an empty password. Press Unlock with the field empty first.
