PDF Password Protector Pro

While you are away from your desk and don't usually lock your computer, any PDF file you own can be accessed copied or modified. If you have important data within your documents, the best way to protect them would be by locking all that info behind a strong and secure password. Online tools may or may not be trustworthy, but standalone desktop apps are, most of the time. PDF Password Protector Pro is a smart little tool that can offer you a swift way of securing documents so your work can be safe from ill-intended individuals.

The interface is built in such a way that there is no need for toolbars, menus, or submenus. Everything you see when you first launch the app is all that is needed to get the job done. Sadly, the tool advertises the drag and drop function, which would be of great help with this kind of process, however, this feature looks to be broken at the moment, so the manual selection remains the only way to load the PDFs.

Also, the tool doesn't limit itself to individual files, meaning that if you have a folder full of documents, you can apply a password to it as easy as it would be with a single file. All you have to do is to check the Folder option from "Type of operation."

After the PDF is ready, choose the restriction permissions (Prevent Copying, Modifying, Printing) and type in the password. Depending on the version of Adobe you run, you might want to check the settings in order to pick the right encryption type. As for the locking methods, you can choose the 128-bit RC4, 128-bit AES, or the 256-bit AES.

In order to finalize the process, you should make sure that the password you've picked is backed-up and restrict permissions are on point. Hit the Protect PDF button in order to generate a new protected PDF file, based on the one you've uploaded. To check the protection status, open the document and wait for the prompt that asks for the key.

To conclude, if you need a compact and intuitive tool that can quickly lock your PDF files, all you need to do is give PDF Password Protector Pro a chance. After several tests, the app had no crashes, freezes, or other issues except for the drag and drop one, which doesn't break the app and will probably be fixed in the next updates.
