You can read PDF, eBook (ePub, Mobi), XPS, DjVu, CHM, and comic books. This lightweight program lets you view PDFs without a lot of extra features that slow things down. There's no need to install the tool, so no changes are made to your system.

Sumatra PDF is an application that enables you to view PDF files, without requiring any third-party components.

Since this is a portable tool, installing it is not necessary. Your Windows registry keys will remain intact and you can also place Sumatra PDF Portable on a removable device and always have it with you when you're on the go.

The user interface of the program is plain and simple, although the default background color (yellow) can be a little disturbing to the eyes.

You can open a document by using the file browser or the "drag and drop" method. Sumatra PDF Portable can handle files in the PDF, XPS, DjVu or CHM format (including comic books).

Thus, you can visualize document properties (e.g. date of creation, PDF producer and version, page size), as well as toggle the viewing mode between single page, facing, book view, "Show pages continuously", presentation and full screen.

Also, you will be able to change the orientation (left and right), go to a particular page, search for text and zoom (e.g. fit page, actual size, fit width, fit content, custom).

Furthermore, you can create a favorites list, change the interface language, disable the program to automatically check for updates or to remember opened files, as well as change the default layout and zoom.
