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

Очень классное дополнение, не только помогает в chromium, где PDF не встроен, но и перешел на него в Chrome потому, что обработка разных PDF из сети при помощи javascript гораздо безопаснее.

[EDIT(7/25/16): Noticed some pages are not rendered corectly. Lowered my rating to 3 stars for this issue.] Good pdf viewer with minimal features. To reach 5 stars, I would like to see: 1)Add capability to edit bookmarks & adjust document outline panel width, 2)Add scrolling in presentation mode, 3) Add option to hide top toolbar header for max vertical screen size, 4)Add option to view facing pages, 5)Add comments

Awesome. I use Chromium, and I especially like the newfound ability to see PDF files right in the browser instead of having them downloaded by default.

One of my favourite PDF-viewers. Only problem is sometimes the text is blurry if you zoom in.

Application parfaite, une des rares qui fonctionne sans se poser de questions contrairement à l'appli officielle de google

zahlreiche PDFs mit eingebetteten Bildern und Grafiken werden nicht oder nur teilweise angezeigt. Schade!
