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

As many mentioned, I'm surprised by the low rating. This extension makes PDF scrolling much much smoother in Chrome, on par with Edge's PDF support (which has always been better than Chrome).

This works perfectly! Chrome default pdf viewer is laggy while Microsoft Edge seemed to have a very smooth refresh rate. This extension changed that. I don't know why the rating is so low. The only con is that the pinch zoom (touchpad) is very sensitive so its better to use Ctrl +/-.

I dont use Acrobat or other softs. This is my preffered way of opening PDFs. Does anything i need, i can rotate, the pages are numbered both in roman (i, ii, ix etc) and arab (1, 2), displays chapters on the sidebar, can zoom in and out easily. 10/10

Works great and works with relative links within PDFS which most embed browser PDF views won't do.

很好用,是否可以增加夜间模式吗,或者自定义背景和文字颜色的功能吗。 Good job, Can you add dark mode, or functions of customizing background and text color.
