Product summary

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

Nice UI and works really well, but all the fonts are terribly aliased compared to chrome's built-in PDF reader on the same file.

I installed it in order to be able to open in a new tab the hyperlinks in a pdf that comes from a ppt and that point to external pages. This feature works perfectly, on the other hand the hyperlinks that point to a slide inside the document don't work correctly. The plugin always adds one page to the link. I'll go back to the default pdf chrome plugin.

Great - needs the ability to Save As instead of strictly saving a file as Document (i) to Downloads each time.

INCREDIBLE! now i can use my chromebook like a tablet to read. I just turn it like if was an open book. I go fullscreen with PDFviewer and just by clicking the mouse pad it goes to next page! It's so comfortable. Great extension Sadly for the native app on chrome, this extension is better. =)

This great PDF viewer is one of the few available that has a true presentation mode when going full-screen. You can therefore use it to give presentations using PDF slides (the stock Chrome PDF viewer has no proper presentation mode).

Very good and practical for the most part. Sometimes crashes. Would be better if there was a print option incorporated
