PDF.js is Portable Document Format (PDF) viewer that is built with HTML5.
PDF.js is community-driven and supported by Mozilla Labs. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.
PDF.js is an open source project and always looking for more contributors. To get involved checkout:

PDF.js is built into version 19+ of Firefox, however two extensions are still available that are updated at a different rate:
- Development Version - This version is updated every time new code is merged into the PDF.js codebase. This should be quite stable but still might break from time to time.
- Stable Version - After version 24 of Firefox is released we no longer plan to support the stable extension. The stable version will then be considered whatever is built into Firefox.
The Chrome extension is still somewhat experimental but it can be installed two ways:
- Unofficial Version - This extension is maintained by a PDF.js contributor.
- Build Your Own - Get the code as explained below and issue
node make extension. Then open Chrome, go to
Tools > Extensionand load the (unpackaged) extension from the directory
You need to have node 0.8.x installed.
Getting the Code
To get a local copy of the current code, clone it using git:
$ git clone git://github.com/mozilla/pdf.js.git pdfjs $ cd pdfjs
Next, you need to start a local web server as some browsers don't allow opening PDF files for a file:// url:
$ node make server
You can also view all the test pdf files on the right side serving
In order to bundle all
src/ files into a final
pdf.js and build the generic
$ node make generic
This will generate the file
build/generic/build/pdf.js that can be included in
your final project. The pdf.js file is large and should be minified for
production. Also, if you would like to support more browsers than Firefox you'll
also need to include
You can play with the PDF.js API directly from your browser through the live demos below:

- Simple reader with prev/next page controls: http://jsbin.com/pdfjs-prevnext-v2/edit#html,live
The repo contains a hello world example that you can run locally:
