Manipulate PDF files for free with PDFRider

PDFRider (currently in version 0.5) is an open source project on Codeplex. This utility provides a GUI for the command-line program Pdftk. It can perform the following operations on PDF files -

• Merge PDF documents 
• Insert pages from PDF file to another 
• Extract pages from a PDF document to a new document 
• Delete pages 
• Rotate pages 
• Crypt and Decrypt a PDF file 
• Burst or split a single, input PDF document into individual pages

I used it to extract summaries of chapters from a PDF eBook & then merge them all together into a mini PDF ebook.

The UI of PDFRider looks amateurish & needs a lot of improvement. I badly missed the keyboard shortcut to save the manipulated files. Considering it's free, open-source & it did the job quickly without errors, I can't really complain though. It felt faster than PDFSAM which I tried a few years ago.
