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".

Can't argue against the possibility to watch PDF-files in my browser directly. Like Firefox can do by installing their extension, we can do now by Chrome too. And we all know: Chrome is way better watching javascript & HTML5 than any other browser - thanks to webkit. So it was only a matter of time, to get it here too - thanks to the great dev Rob W. Well done Rob!

I have to say, I really like the idea of this Extension. I try to disable as many native components as possible, and an HTML5 pdf reader tickles me pink. I used this for a while as both my web and desktop PDF viewer, and the UI is absolutely great. There are a couple important caveats however. Firstly, for most PDFs it's fine, but with more complicated PDFs, the performance is definitely not up to the native plug in - lagging on page scroll (it seems to generate a lot of waste HTML). Finally, the extension cannot seem to read PDFs from anything but an HTTP GET request. It's rare that I need this functionality, but it has proven an obstacle. Overall, great with some room for improvement under the hood. I ultimately had to uninstall because my college library uses POST for secure pdf delivery, but I will definitely be watching closely.

Better out of the box than just about any other PDF app or extension.

I was looking for a PDF reader that could do one simple thing: copy and paste from the PDF document without issue. Sadly, most of the PDF viewers cannot do this simple thing, and I have been searching for ages for a reader that could do it. Really I think it's pathetic that Google's built-in viewer can't even accomplish simple copy-paste functions, but fortunately I've finally found an extension that can accomplish such an elementary and essential function!
