I love Aspose.Pdf!
I was using another pdf toolset but it was overly complex to do the most basic things and the files it generated was massive. My software reads pdf text values and then splits the pdf based on a text lookup. I then email the results. I was trying to email massive files but now I am using Aspose.Pdf I get nice small files that email faster and don't waste less bandwidth. Seriously I spent days searching for help on pdf optimisation and a few lines of codes as shown in the samples sorted my problem. One example pdf down from 4Mb to 90 Kb.

The documentation is a real stand out feature with Aspose.PDF. There are so many examples to show you how it works and they are all nicely commented making life super easy. I prefer to learn by example so I found these a life saver.

I have converted my application in an afternoon and now my code is so much more readable thanks to the clear and concise structure I really cannot recommend his product enough.
