PDF.jsPDF.js is a 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.

FirefoxPDF.js is built into version 19+ of Firefox, however one extension is still available:
- 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.
Chrome and Opera
- The official extension for Chrome can be installed from the Chrome Web Store.
- Opera has also published an extension for their browser at the Opera add-ons catalog.
- Build Your Own - Get the code as explained below and issue
node make chromium. Then open
Tools > Extensionand load the (unpackaged) extension from the directory
Getting the CodeTo get a local copy of the current code, clone it using git:
Next, install Node.js via the official package or via nvm. If everything worked out, run
$ git clone git://github.com/mozilla/pdf.js.git $ cd pdf.js
to install all dependencies for PDF.js.
$ npm install
Finally you need to start a local web server as some browsers do not allow opening PDF files using a file:// URL. Run
and then you can open
$ node make server
It is also possible to view all test PDF files on the right side by opening
Building PDF.jsIn order to bundle all
src/files into two productions scripts and build the generic viewer, issue:
This will generate
$ node make generic
build/generic/build/directory. Both scripts are needed but only
pdf.jsneeds to be included since
pdf.worker.jswill be loaded by
pdf.js. If you want to support more browsers than Firefox you'll also need to include
build/generic/web/. The PDF.js files are large and should be minified for production.
LearningYou can play with the PDF.js API directly from your browser through the live demos below:
The repo contains a hello world example that you can run locally:
