We purchased NXPowerLite for Servers to address the large number of bloated PDF files we work with. The software is simple to install and configure. The licensing model is simple and a great value. Our use is only for PDFs and we used the default optimization settings. With the default settings, we achieved a 65% reduction in space used by PDF files. I've attached a sample before/after of one of our folder structures. We ran a large test on a non-production copy of several folders and found the optimized PDFs to be of great quality - in most cases, the optimized PDF was indiscernible from the original. I had a handful of question for support and they responded quickly with accurate answers to my questions. A+
