PDFtk is a simple tool for doing everyday things with PDF documents. It comes in three flavors: PDFtk Free, PDFtk Pro, and our original command-line tool PDFtk Server. PDFtk Free is our friendly graphical tool for quickly merging and splitting PDF documents and pages. It is free to use for as long as you like. Use PDFtk Pro to quickly split, merge, rotate, watermark, stamp and secure PDF pages and documents. PDFtk Pro is a graphical application that makes working with PDFs as easy as possible. PDFtk Server is our original command-line tool. It is commonly used for server-side processing of PDFs. It is also used by many PC software publishers to give their products the ability to manipulate PDFs.
