PDF.js
PDF.js is a Portable Document Format (PDF) library that is built with HTML5. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.
This is a pre-built version of the PDF.js source code. It is automatically generated by the build scripts.
See https://github.com/mozilla/pdf.js for learning and contributing.
