Simplicity of the user interface has a high priority. PDF readers have, over the years, managed to earn themselves something of a reputation for being slow, lumbering beasts - thanks largely to Adobe Reader. Sumatra PDF bucks the trend. It is small, svelte, lightweight and lightning fast.

Pros from Real Users Pros The best kind and fast service. in every inquiry I always receive a professional response. Great Tool! After evaluating several other replacements for our current PDF solution, RAD PDF is the best fit by a large margin. The architecture is a very close fit to our current solution and will require very little conversion. Support for signatures was a key feature we were looking for, and RAD PDF provides solid signature support.		Pros & Cons from Real Users Pros Folks at adobe should learn coding from these guys. I gave up on Adobe Reader as: 1. Its scrolling speed was less than satisfactory at zoom level other than 100%, for long pdf files, for graphic heavy pdf files with images and/or mathematical notations. 2. It would always reduce document window space in by incorporating various toolbars to the right/bottom at opening time. 3. It would also not remember last opened page view by default. 4. Shameless popups of adobe paid services and digital signature warnings. Sumatra PDF does not have any of these problems. Free and open source. Minimal User Interface - Easy to use. Supports pdf, epub, mobi and other formats. Low memory usage and quick to load files. Portable software. Cons Advanced settings opens a notepad file, containing sensitive settings, that, if edited incorrectly, may break the program. Would be better to make it a GUI based menu. Doesn't support editing. The design is outdated (No annotations as well).
