Yes for user-password files — enter it once per file. This removes restrictions from files you own; it cannot crack unknown passwords.
Owner passwords (print/copy limits) remove instantly with the password; user-password files need it to open at all. Both stay local — passwords never upload.
For files you own or are authorized to process, yes. Bypassing others' protections without permission violates law in most jurisdictions — this tool assumes your ownership.
No — unlocking runs locally in your browser. Passwords never leave your device; saves download with no quota.
No — unlocking re-renders each page as a JPEG image inside a new PDF, so text is no longer selectable or searchable. Links and form fields do not survive either; keep the original for editing and use the unlocked copy for reading and printing.
