PDFTK Builder Enhanced is a tool to combine (collate), split, decrypt, add background/stamp, password protect PDF files etc. It is a GUI frontend to the command-line PDFtk.

Note that this project is a fork of Version 3 of PDFTK Builder by Angus Johnson to:

• Enhance the user interface
• Add PDF operations and options
• Update the program to be compatible with later versions of PDFtk

As such, it can be considered as a major upgrade to the original program.
