== History and Application ==

PDF.js can work as a part of a website or of a browser.

Developers will also embed PDF.js in their software in order to enable PDF rendering and viewing in a web or native application, or rendering on a server. Examples of PDF.js integrations include within [[Dropbox (service)]] for PDF document previews,<ref> https://dropbox.tech/application/annotations-on-document-previews</ref> [[Slack (software)]],<ref>https://slack.engineering/what-matters-to-you-matters-to-us-10ff49650a5d</ref> and Linkedin for viewing accessible course materials online.<ref>https://engineering.linkedin.com/blog/2019/04/under-the-hood--learning-with-documents</ref> Some software development products are also based on making it easier to extend PDF.js.<ref>https://news.ycombinator.com/item?id=22763656</ref><ref>https://pdfjs.express/blog/introducing-pdfjs-express</ref>

==Behavior==

According to one benchmark, PDF.js is performant for viewing most common PDF files, while it may have some issues with large or ‘graphics'graphics-heavy’heavy' documents. <ref>https://hacks.mozilla.org/2014/05/how-fast-is-pdf-js/

</ref>

Another analysis found that between 1-3% of PDFs in certain document subsets would crash or freeze the PDF.js viewer, either due to a corrupted file or a complex file.<ref>https://www.pdftron.com/blog/pdf-js/pdf-js-reliability-benchmark/ </ref>

PDF.js supports most of the PDF specification, but some features have not been implemented yet, which may impact rendering behavior depending on the features the document uses.<ref>https://www.pdftron.com/blog/pdf-js/guide-to-pdf-js-rendering/</ref>

*Interactive and fillable forms

The PDF.js contributor community also notes that the browser behavior of PDF.js varies with browser support for PDF.js’sjs's required features.<ref>[https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#which-browsers-are-supported ]</ref> Performance and reliability will be the best on Chrome and Firefox, which are fully supported and subject to automated testing.
