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

Slow load, and added a blank page in-between each PDF page when asked to print.

Loads PDFs quickly but frequently changes zoom to 25% during scrolling, and prints blurry unreadable blobs.

This is a very good pdf viewer. The zoom works well and everything renders really well. Printing & saving are easy, as is rotation both ways. The only improvement I can suggest is to offer a dual page view as well as a continuous one.

This helped me while the Chrome PDF Viewer plugin gave up loading/downloading PDF files on the browser. Thanks!!
