# PDF.js

Unclassified · [Official website](https://mozilla.github.io/pdf.js/)

PDF.js is an open-source JavaScript library from Mozilla that displays PDF documents directly in the web browser using HTML5, without a plugin. It powers the built-in PDF viewer in Firefox and is embedded by many websites to show documents. It runs on the client side as part of the site and does not send data to a third-party service by itself.
