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".

Awful. Somehow it's even slower than Adobe's reader. I didn't think that was possible. And the resolution when zoomed out is abysmal. Avoid.

Fantastic! It actually works. I haven't been able to view a PDF in the browser for forever so the fact this works makes me brilliantly happy!

Bad resolution. Impossible to read documents unless you zoom in at 200%.

This extension actually WORKS - even inside an IFRAME (unlike the extension from Google!)

perfekt, super schnell und easy. Damit muss man nicht erst mühselig runterladen sondern sieht den Inhalt schon im Browser Fenster.

If you have hightlighted text from e.g. Adobe Acrobat with a background color, the text is hidden by the background color, when you see the document in this pdf viewer in Chrome. But it isn't a problem in the default Chrome pdf viewer.
