Sumatra PDF 2.5.2

Sumatra PDF is a free open source PDF reader that can also work with many other ebook, text and comic book archive files (Mobi, ePub, DjV, CHM, XPS, CBR and CBZ). This lightweight and fast reader was created for maximum comfort and useful features, especially targeting users who have either very slow computer that is struggling whenever users start up official PDF viewing application Adobe Reader, or to enable users with small technical knowledge to easily get access to all tools that are needed for reading PDFs. Some of its most notable features are ability to be used as a portable application that is housed on external storage device (no installation required), PDF editing and saving, printing, over 69 language translations, and more.

As you would expect from this lightweight and very fast app, the main interface of Sumatra PDF is crafted from the ground up to be as easy to use as possible, with minimal amount of on-screen tools being available on the top of the app (Search, Print, go to Page, next page, previous page, few modes of rendering pages, zoom and keyword Find). There are no complicated tools, no ways of making user confused, and even context sensitive properties menu of the app offers just basic controls that can be easily managed by anyone. Customization screen of the app offers minimal tools for setting automatic zoom level, default layout and nothing much more. All in all, Sumatra PDF is a perfect PDF viewing app for beginners and users with slow PC configurations.
