collective.pdfjs - Plone integration for Mozilla's JavaScript PDF reader


This product adds pdf.js support for Plone.

Pdf.js is a JavaScript library for rendering PDF documents in the canvas, without using external plugins; only JavaScript is needed.

This product will make the JavaScript library available as a resource, and add a new view for the File content type.

Please note that pdf.js is still under heavy development; as such:

  • a modern browser is required;
  • not all PDFs may be rendered correctly, or at all;


Using zc.buildout add collective.pdfjs to the list of eggs to install:

recipe = plone.recipe.zope2instance
eggs =

Re-run buildout, e.g. with:

$ ./bin/buildout

Restart your plone instance and install this addon.


If the view detects a PDF file, it will attempt to render it inline using pdf.js. If the user browser doesn't have JavaScript enabled, it will embed any available PDF reader plugin (Acrobat's, Google Chrome native, etc) instead.

Additional information

Currently, the whole document is downloaded and each page rendered incrementally inside the canvas. This means that big files on slow connections will take a while before displaying; you might want to switch to the standard view in this case.
