A general-purpose, web standards-based PDF viewer built with HTML5 and JavaScript.
PDF.js is an open-source JavaScript library that renders PDF documents directly in web browsers using HTML5, without requiring plugins like Adobe Reader. It provides a platform for parsing, rendering, and manipulating PDFs programmatically, making PDFs accessible across modern web environments. The project is community-driven and supported by Mozilla, focusing on web standards and broad compatibility.
Web developers and organizations needing to embed PDF viewing capabilities into websites or web applications without relying on proprietary plugins. It is also valuable for browser extension developers and those working on document-heavy web platforms.
Developers choose PDF.js because it eliminates dependency on native PDF plugins, offers a robust and extensible API for custom integrations, and is built on open web standards. Its community-driven development and Mozilla backing ensure reliability and continuous improvement.
