As an Ubuntu Linux user if you’re searching for an extremely simple PDF editor (sort of) then PDF Shuffler is a pretty decent utility. However that tool can only let you change page order, split and merge PDF documents.
So if you’re looking for a more powerful tool that lets you easily merge, split, encrypt documents, edit meta-tags including few more other features, then try ‘PDF Chain’.
In truth, PDF Chain actually uses a command-line tool called “PDF tool-kit” (known as “pdftk”), but PDF Chain does make everything so much easier and user friendly because it’s a GUI tool.
*. Split and Merge PDF files.
*. Rotate pages.
*. Add a background or a stamp (watermark logos) to the PDF. Excellent for “branding” purposes.
*. Set output permissions (read-only, read & write, restrict copying, printing etc).
*. Add attachment to the whole PDF document or individual pages and extract attachment from PDF files.
*. Generate FDF data.
*. Update PDF meta-data.
*. Fill forms … are among its main features.
You can install PDF Chain in Ubuntu 12.04 Precise Pangolin, 11.10 Oneric Ocelot, 11.04 Natty Narwhal, 10.10 and 10.04 by using the below command in your Terminal window.
sudo apt-get install pdfchain
It also uses very little of your system resources due to its simplicity and good coding:).
Now this is not a PDF creation suite and only a simple editor, but after all is said and done, PDF Chain is an elegant little application!.
