Free PDF File Viewer (Small, Open Source, Portable)

Too bad the popular Adobe Reader has some disadvantages that make many keep searching for the better alternatives. It may be a good PDF viewer for an advanced PDF document, but may be not for a standard one involving only texts and pictures in simple formats. For you who need the alternative, try this Sumatra PDF Portable.

Many has appreciated it as a free handheld PDF viewer that fast, small in size, free to download, and can be used in portable devices (USB flash drive, iPod, portable hard drive, CD, pocket pc, or others). The interface is very simple as you can see from the picture. It doesn't have many features, too. What you can get from it are only the standard tools that you need in reading a document (zoom, navigation, search, etc). It is understandable, then, if it is admitted as one of the fastest PDF viewers.

You need to install this software first, then you can add it into your portable devices. It requires Windows 95/98/Me/2000/XP/Vista.
