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

    History and application

    [edit | edit source]

    PDF.js was originally created as an extension for Firefox[3] and is included in Firefox since 2012 (version 15),[4][5] and enabled by default since 2013 (version 19).[6][7] It was added to Firefox for Android in 2023 (version 111).[8]

    The project was created to provide a way for viewing PDF documents natively in the web browser, which prevents potential security risks when opening PDF documents outside a browser, as the code for displaying the document is sandboxed in a browser.[9] Its implementation uses the Canvas element from HTML5, which allows for fast rendering speeds.[9]

    PDF.js is also used in Thunderbird,[10] ownCloud,[11] Nextcloud,[12][13] and is available as a browser extension for Google Chrome/Chromium,[14] Pale Moon[15][16] and SeaMonkey.[16][17]

    It can be integrated or embedded in a web or native application to enable PDF rendering and viewing, and allows advanced usages such as Server-side rendering.

    Many web applications, including Dropbox,[18] Slack,[19] and LinkedIn Learning[20] integrate PDF.js to enable previewing PDF documents.

    Behavior

    [edit | edit source]

    According to a benchmark by Mozilla, PDF.js is performant for viewing most common PDF files, while it may have some issues with large or 'graphics-heavy' documents.[21]

    PDF.js supports most of the PDF specifications (including form support or XFA[22]), but some features have not been implemented yet, which may impact rendering behavior depending on the features the document uses.[23]

    Several PDF/X or optional PDF features that are not supported in PDF.js include:

    The PDF.js contributor community also notes that the browser behavior of PDF.js varies with browser support for PDF.js's required features.[27] Performance and reliability will be the best on Chrome and Firefox, which are fully supported and subject to automated testing.
