Sumatra PDF is a free and open-source document viewer that supports many document formats including: Portable Document Format (PDF), Microsoft Compiled HTML Help (CHM), DjVu, EPUB, FictionBook (FB2), MOBI, PRC, Open XML Paper Specification (OpenXPS, OXPS, XPS), and Comic Book Archive file (CB7, CBR, CBT, CBZ). If Ghostscript is installed, it supports PostScript files. It is developed exclusively for Microsoft Windows, but it can run on Linux using Wine.
Sumatra has a minimalist design, with its simplicity attained at the cost of extensive features. For rendering PDFs, it uses the MuPDF library.
Sumatra was designed for portable use, as it consists of one file with no external dependencies, making it usable from an external USB drive, needing no installation.This classifies it as a portable application to read PDF, XPS, DjVu, CHM, eBooks (ePub and Mobi) and Comic Book (CBZ and CBR) formats.
As is characteristic of many portable applications, Sumatra uses little disk space. In 2009, Sumatra 1.0 had a 1.21 MB setup file, compared to Adobe Reader 9.5’s 32 MB. In January, 2017, the latest version of SumatraPDF, 3.1.2, had a single 6.1 Mb executable file; in comparison, Adobe Reader XI used 320 MB of disk space.
The PDF format’s use 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 accord with its principles of interoperability and re-use.
Through version 1.1, printing was achieved by rasterizing each PDF page to a bitmap. This resulted in very large spool files and slow printing.
Since version 0.9.1, hyperlinks embedded in PDF documents have been supported.
Sumatra is multilingual, with 69 community-contributed translations.
Sumatra supports SyncTeX, a bidirectional method to synchronize TeX source and PDF output produced by pdfTeX or XeTeX.
Since version 0.9.4, Sumatra supports the JPEG 2000 format.
