How unlocking works here

Drop the file. If it needs a password to open, the page asks for it. The password is used in this tab only.
Unlock. The engine opens the file with the password and writes it back without the encryption dictionary.
Download. An open copy, the same pages, text and images, checked by re-opening it.

What it does

Removes the password to open, when you have it.
Removes owner restrictions (no printing, no copying) from a file that opens without a password.
Keeps everything else: bookmarks, forms, metadata.

What it does not do

It does not guess or crack a password; without the password the file stays closed.
It is for files you own or are allowed to use; removing restrictions from someone else's document may be against their licence or the law where you are.
It does not remove a digital signature.

Questions

I do not know the password. Can it still open?

No. The password is the key the file is encrypted with; there is no way round it and this site does not try.

The file opens but will not print or copy. Is that a password?

That is an owner restriction. The file opens without a password and this tool writes a copy without the restriction.

Is it legal?

For your own files and files you are allowed to use, yes. For a document someone else protected, check their terms; the restriction may be part of a licence.

Does my password leave my computer?

No. It is used by the engine in your browser tab and discarded. The site has no server that could receive it.
