pdf-Recover is an easy-to-use Mac application that, as you can easily get from its name, helps you remove the limitations of any PDF document that you might have stored on your system. This simple tool can come in handy, especially if you have forgotten the master password of your encrypted PDF file (can recover up to 256-bit AES encryption).
In order to remove the limitations of a PDF document by using the pdf-Recover, all you have to do is to click on the "Recover document" or drag-and-drop the file directly to the interface. Once you have done that, this application will instantly create a copy of your original PDF document, which you can easily edit, print or copy without having to deal with any security problems.
This application comes with a simple and minimalistic interface and the lack of any menus or settings keeps the job of removing the restrictions of your PDF files simple and straight to the point.
Keep in mind that, if your PDF files have user-level passwords or they were protected with the help of other applications, pdf-Recover won't be able to recover them. The same goes for eBooks that require Adobe Digital Editions.
To sum it all up, if you are ever in need of an easy-to-use Mac application that can help you remove the limitations of your PDF files, then you might want to take a look at the pdf-Recover.
