About
Sumatra PDF is a free PDF, eBook (ePub, Mobi), XPS, DjVu, CHM, Comic Book (CBZ and CBR) reader for Windows. 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.
