PDF Unlock permits you to remove passwords and ease restrictions from PDF files.This simple tool can help speed up PDF editing by allowing you to remove a previously set password for whatever reason which if you work with PDFs having to enter a password can be a bit tedious. Now that said, this is not a way to get into a PDF that you do not know the password to. It is meant to help streamline the process of working with them by eliminating the need to continuously enter a password.PDF Unlock comes packaged within a very simple UI that is straight to the point. It supports the unlocking of multiple PDF documents at once as long as they have the same password, drag n' drop, saving of unlocked PDF documents in the same folder (specified suffix required), and it has the option to overwrite the original PDF document(s) with an unlocked document(s).
