Overview

Product summary

Review the store description, core capabilities, and common use cases.

PDF.js is a Portable Document Format (PDF) viewer that is built with HTML5.

PDF.js is community-driven and supported by Mozilla. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.

This extension offers PDF.js as the default PDF viewer in Chrome. This is the official Chrome extension of the PDF.js project. Be careful of unrelated copycats.

If you want to use this viewer to view local files, visit chrome://extensions/?id=oemmndcbldboiebfnladdacbdfmadadm and put a check before "Allow access to file URLs".

Please report any issues at https://github.com/mozilla/pdf.js/issues

Great Extension!!! I noticed that the program was not allowing Dropbox files to open properly so I emailed Rob, he fixed the issue and had the new version, which works perfectly with Dropbox, up in the Web Store within 2 hours!!! Great product and service!

If I use Ctrl+MouseWheel, I seem to use the browser's zooming instead of the viewers scaling mechanism. It would be awesome if that could be fixed, i.e. if Ctrl+Mousewheel would trigger the viewer's zooming. Otherwise, a very good extension.
