It was originally written for the [[Software:Sharp Zaurus|Sharp Zaurus]] and currently runs on many other [[Engineering:Mobile device|mobile device]]s, like the Nokia Internet Tablets, as well as [[Engineering:Desktop computer|desktop computer]]s. A preview of FBReaderJ (the [[Java (programming language)|Java]] port) for Google [[Software:Android (operating system)|Android]] was released on April 13, 2008.

Supported formats include [[EPUB]], [[FictionBook]], [[HTML]], [[Software:Plucker|plucker]], PalmDoc, zTxt, TCR, [[Software:Microsoft Compiled HTML Help|CHM]], [[Rich Text Format|RTF]], [[Open eBook|OEB]], [[Company:Mobipocket|mobi]] without [[Engineering:Digital rights management|DRM]], and plain-text.<ref>[http://fbreader.org/about.php FBReader: About FBReader]</ref>

It was formerly [[Free software|free software]] under the GPL, but since 2015 (v2.7) is proprietary software.<ref>{{Cite web|url=https://fbreader.org/android|title = FBReader for Android|date = 10 July 2011}}</ref>

== History ==
Nikolay Pultsin wrote the first FBReader; the tool was released for the [[Software:Sharp Zaurus|Sharp Zaurus]] in January 2005, a [[Software:Maemo|Maemo]] port was added{{by whom|date=June 2016}} in December 2005 for the Nokia 770. FBReader has since had binary packages released for many mobile-device platforms and for most major personal computer operating systems.<ref>{{Cite web |url=http://fbreader.org/obsolete/ |title=FBReader: obsolete versions |access-date=2008-07-01 |archive-url=https://web.archive.org/web/20080724021816/http://www.fbreader.org/obsolete/ |archive-date=2008-07-24 |url-status=dead }}</ref>
The FBReader name with the [[FictionBook|FB]] prefix comes from [[FictionBook]], an e-book format popular in Russia, the country of FBReader's author.<ref>[http://talk.maemo.org/archive/index.php/t-555.html FBReader and its .fb2 format], maemo.org forum, 2005</ref>

The original FBReader was written in C++; however, in 2007<ref>{{Cite web |title = geometer/FBReaderJ |url = https://github.com/geometer/FBReaderJ/tree/23c429502a1ae00bde925b8fc9e17bde2a3ba5cf |website = GitHub |access-date = 2015-07-03}}</ref> a fork called FBReaderJ was created{{by whom|date=June 2016}}, which was written in Java. As the Android platform became available in the following years, this fork became the codebase for the Android software application, while the C++ codebase remained in use for other platforms.<ref>

In 2015 the software for all platforms became closed-source: the old open-source code hasn't been updated since.  The Android app was split into Free and Premium versions, both closed-source, with the Premium version adding integrated support for [[PDF]] and for [[Machine translation|machine translation]].<ref>{{Cite web|url=https://fbreader.org/android|title = FBReader for Android|date = 10 July 2011}}</ref>
