PDF.js or pdf.js is a JavaScript library that renders Portable Document Format (PDF) files using the web standards-compliance HTML5 Canvas. The project is led by the Mozilla Foundation after Andreas Gal launched it (initially as an experiment) in 2011.

PDF.js can work as a part of a website or of a browser. Originally created as a Firefox extension,[3] it is now included in Mozilla Firefox since 2012 (version 15)[4][5] and is enabled by default since 2013 (version 19)[6][7]. SeaMonkey users need to install the development version of the extension. It is also part of ownCloud and there exists a browser extension for Google Chrome and Chromium.[8]
