jPdf Tweak is a swiss army knife for PDF files, a Java Swing application that can combine, split, rotate, reorder, watermark, encrypt, sign, and otherwise tweak PDF files. You can use it to make printable booklets from your PDFs, to add PDF bookmarks, effects (page transitions), to combine multiple PDF files, to watermark them, to rotate pages that do not fit, to attach files to your PDF, to encrypt and sign your PDFs, to change metadata (like author or keywords), and much more.

Start jPDF Tweak by running jpdftweak.bat, double-clicking jpdftweak.jar or running "java -jar jpdftweak.jar" at the command line.

Select an input file to manipulate. If you want to combine multiple files, check the checkbox and add more files. They will end up in the box below, where you can select pages and/or reorder them. Click Add in the lower left corner to add another entry for a file already used.

If the file is encrypted, you will need the owner password to decrypt it. All page numbers start with 1 (like normal people count), not with 0 (like programmers count).

Requirements:
* Java
