Review & Alternatives

"A open-source PDF viewer."


Sumatra PDF is an advanced reader that is capable of opening not just PDF files, but also e-books, and comic books. The software maintain simplicity while providing access to the most important features that most users are concerned with.


Installing this free PDF reader is as easy as using it. Simply download the tiny setup file, follow the wizard style guide, and in minutes you'll be reading digital content. System requirements are minimal, as it can be used on any computer that has a modern version of Windows installed.


The Sumatra PDF interface is surprisingly primitive, with very few options and features to choose from. As a basic PDF/e-book viewer it serves its purpose well, providing access to all of the basis functions you would expect, including button icons for scrolling through pages and zooming in and out. As with every other PDF viewer, there is also a find box in the top rigsht corner of the main window that lets you find specific text within a file.


  • Comes in a small portable package that starts up quickly and performs at high speeds every time

  • Commandline functionality gives advanced users the ability to perform functions easily using convenient text commands

  • Open source coding structure makes it possible for any skilled developer to extend and enhance functionality through plugins and user interface tweaks

  • Quickly print a page by clicking the print icon in the top left corner.

  • The settings menu lets you adjust how the software deals with certain types of files and change default behavior

  • Can display a variety of file types, including PDF, MOBI, CHM, XPS, CBZ, CBR, and DjVu files

  • The Find function makes it easy to locate a particular word or phrase within a document of any size

  • The developers are constantly putting forth a collective effort to improve the software by accepting complaints, acknowledging bug reports, and taking recommendations for feature enhancements


  • The user interface looks a bit old-fashioned, and the top toolbar doesn't really have too much to offer. However, all the features you need to enjoy interactive text documents are included.


There are many other PDF/e-book readers available online, the most popular of which include Foxit Reader, Adobe Reader, and Nitro PDF Reader. Of these competitors, Adobe Reader is by far the most popular, with Foxit and Nitro PDF following in second and third place respectively. If you're looking for a more comprehensive PDF reader solution, you may want to go with either Adobe or Foxit. However, if you simply need a free application that can display all e-books, comic books, and PDFs, Sumatra PDF would be a suitable addition to your software collection.


As a software that can display almost every type of digital book content, Sumatra PDF is an often overlooked application that is certainly capable of accommodating most people's needs and preferences. With just enough functionality to please the average user, this simplistic utility doesn't overwhelm with unnecessary features.
