About

Open PDF files in a focused Windows viewer that starts quickly and keeps attention on the page. SumatraPDF also reads EPUB and MOBI ebooks, along with FB2 files for users who keep books in several ebook formats. It displays CBZ and CBR comic-book archives, and opens CHM, XPS, DjVu, and image files in the same application.

The program is useful for reading documents, ebooks, comics, and reference material without switching between format-specific viewers. Its interface is deliberately simple, making page-based reading and file viewing straightforward rather than surrounding them with unrelated tools. Quick startup is especially convenient when a file needs to be opened briefly for consultation.

SumatraPDF targets people working on Windows who want one compact reader for mixed document collections. The current 3.6.1 release is built for x64 Windows systems and is distributed under an open-source license. Krzysztof Kowalczyk is the developer and publisher behind this System Tools utility.
