Sumatra PDF is powerful, small, portable and starts up very fast. 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 & Cons from Real Users Pros Very comprehensive set of APIs that allow the developer to create complex applications. The support has also been excellent. A very high quality SDK for all things PDF. As I understand it, it's based on the same code that Adobe products (e.g. Acrobat) use for PDFs, with some additions. That makes it essentially the reference SDK for PDF. The included support can be very helpful. Can be used with C#, Java, and C++. - It has one of the largest collections of PDFs. - There is a lot of variety for all the genres. - It has an easy and simple UI. Adobe PDF library is a nice and fancy tool. It has a lot of options and choices to choose from. Recommended. It makes it easy for managing documents. It offers files type conversion with a PDF reader. Very easy to use. Easy to create, edit documents and read large PDF files. Cons Because there are so many APIs, it takes a while to fully understand them and how they are used together. It's for-pay closed-source software. Has a bit of a learning curve to get started, at least when used with C++. Probably not a good match for very small projects. - The price of the software and PDFs is quite expensive. I liked the platform so far. I don't have any cons as such. It worked great for me. Nothing to share about cons.	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).
