Free and open source PDF viewing software download, reviewed by Fernando Ortega

An excellent and recommended PDF reader which is fast and lightweight.

The web has been long annoyed by the complexities and slow performance of the various different PDF viewers available and especially the reader produced by Adobe. In the case of Sumatra PDF, you really do get a basic PDF reader that's not only fast but stable.

Bigger isn't always better and some have said and it couldn't be truer in the case of Sumatra PDF. It's a small and lightweight PDF reader which not only uses very little resources but also provides for a quick and effortless way to view PDF documents. Sumatra is also capable of reading eBooks (ePub, Mobi), comic book files (CBZ, CBR), XPS documents and others.

The layout of Sumatra PDF doesn't include any special features and provides some of the most basic features anyone could want from a PDF reader such as zoom-in/zoom-out, page jumping, basic settings, scrolling and naturally viewing of PDFs. It can also search through documents which is handy.

You can also have Sumatra PDF automatically check for updates if you insist on remaining at the bleeding edge, but due to its basic functionality, there really aren't that many updates being released too often.

Overall, Sumatra PDF is a nice breath of fresh air which provides an excellent lightweight solution for reading PDF files without having an impact on system performance or worse, bogging down your system with "additional offers." We highly recommend uninstalling Adobe Reader and replacing it with Sumatra PDF.
