All About PDF 3.2032

All About PDF is a multi-threaded 64-bit application that utilizes your computer's multiple CPU cores for blazingly speedy PDF processing.
All About PDF can take multiple PDF files and merge them into a single file. You can also go the other way by taking a single PDF file and splitting it into multiple documents. This is done by either specifying multiple page ranges to split by or you can simply tell the application to split the PDF every N pages (for example, you can split a PDF from pages 1 to 5 and 6-10 or just every 3 pages).
You can add Owner and User passwords to your PDF using 256-bit encryption. With an Owner password set on your PDF, you can specify user permission such as:
ability to copy from the document
ability to print the document
ability to annotate the document
ability to modify the PDF attributes
ability to modify the PDF contents and more
