A lightning-fast, fuss-free PDF reader with an uncluttered interface and a few extra tricks up its sleeve.
Sumatra PDF is a free PDF reader optimized for speed and ease of use. There are no fancy extras – just the essentials for viewing PDFs and ebooks, navigating, searching and organizing them. As an added bonus, Sumatra PDF is also available in a portable edition so you can stick it on a USB drive and take it with you to use on other computers.
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.
