PDFTools – A Useful PDF Management Application
PDFTools is a simple-to-use program that comes equipped with a few essential tools for PDF management, such as merging and splitting. This application does not require the installation of a PDF reader, such as the one from Adobe.
The interface of the program is simplistic and easy to navigate through. So, you can encrypt a PDF file, set allowed permissions (e.g. printing, screen reader, modify contents, assembly) and choose the encryption strength.
But you can also decrypt and merge PDFs, rearrange them (all pages, multiple pages on one page, handout pages), stamp a PDF with an image or text, as well as create a PDF document from XML.
