SumatraPDF, also known as Sumatra, is a free and open-source software PDF reader for Microsoft Windows only. The program also opens Open XML Paper Specification, DjVu, EPUB, XPS, CHM, CBZ and CBR, and MOBI files. It is written by Krzysztof Kowalczyk (an alumnus of Télécom Bretagne in 1998).
Sumatra has a minimalistic design, with its simplicity attained at the expense of extensive features. For rendering PDFs it uses the MuPDF library.
Sumatra was designed for portable use, as it consists of one single file with no external dependencies, making it usable from an external USB drive. This classifies it as a portable application. As is characteristic of many portable applications, Sumatra takes up little disk space. It has a 4.2 MB setup file, compared to Adobe Reader's 36.1 MB. Install size is 8.2 MB, whereas Adobe Reader requires 320 MB of available disk space.
When re-opening a document, the rotation, zoom, window size, page, etc. are remembered from the last time that document was opened, making it behave more like an e-book reader than other PDF viewers.
Sumatra does not lock the PDF file. Without closing the PDF file, a user can save over the PDF and then press the R key to refresh the PDF document. For example, a PDFTeX user could find this feature useful when, after recompiling the altered TeX source code, he/she could simply press 'R' and view the altered document.
The PDF format's usage restrictions were implemented in Sumatra 0.6, preventing users from printing or copying from documents that the document author restricts, a form of Digital Rights Management. Kowalczyk stated "I decided that [Sumatra] will honor PDF creator's wishes". Other open source readers like Okular and Evince make this optional, and Debian patches software to remove these restrictions, in accordance with the open source principles of interoperability and reuse.
Since Sumatra 0.9.1 hyperlinks embedded in PDF documents are also supported.
As it was initially designed when Windows XP was the current version of Windows, Sumatra has some incompatibility issues with earlier versions of Windows. Support for Windows 95, 98 and Me has since been dropped completely.
Kowalczyk has not released a 64-bit version of Sumatra, indicating that while it might offer slightly more speed and more memory available it would greatly add to user confusion and that the benefits do not outweigh the potential costs.
The Sumatra source code is hosted on Google Code and because of US export legal restrictions is thus not available "in countries on the United States Office of Foreign Assets Control sanction list, including Cuba, Iran, North Korea, Sudan and Syria."
The first version of Sumatra PDF, designated version 0.1, was based on Xpdf 0.2 and was released on 1 June 2006. It switched to Poppler from version 0.2. In version 0.4 it changed to MuPDF because of speed improvement and better support for the Windows platform, since Poppler decided to focus on integration with Unix platforms. Poppler remained as alternative engine, and from version 0.6 it was automatically used to render pages that MuPDF failed to load. Poppler was removed in version 0.9, released on 10 August 2008.
Version 1.0 was released on 17 November 2009 after more than three years of cumulative development, and version 2.0 was released on 2 April 2012, over two years after the release of version 1.0.
The first unofficial translations were released in 2007 by Lars Wohlfahrt before Sumatra PDF got official multi-language support.

"The Sumatra PDF Viewer is a tiny open source portable reader that opens PDF's in the blink of an eye. Bloat and startup time is a major drawback to Adobe Reader, so we fled to the faster arms of Foxit Reader long ago. However, at 850KB, Sumatra is way slimmer than FoxIt."
