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".

I moved from Adobe Reader to this chrome extension due to many annoying bugs. I need only two things - (1) display the PDF and (2) remember the page when I open it next time. from my experience the (1) works very well, but the (2) does not always work, in most cases it show page which I read few days ago. dear developers, please fix this essential feature computers and IT in general are our biggest problem, I do not think people are able to write 100% error free code

0 issues or problems. Smooth, fast, not sure why it has such a low rating.

Recommended software. Solved one of the major problems with chromebooks for me. All other pdf viewers I have tried are utterly due to excessive lagginess, seconds and more. This one updates pages OK, also seems to do a much better job of navigating page numbers.

Out of date. The latest PDF.js has newer features. This extension hasn't been updated since 2019!

You can start from where you red the last page 5/5!
