Quick answer

What does Unlock PDF do?

Use the known password to create an unprotected PDF copy from a file you own or are authorized to modify. The selected protected PDF and password are processed locally in this browser without being sent to a backend conversion server. The tool does not bypass unknown passwords and should be used only on authorized documents.
