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

This app is great. Has a lot of the small features other pdf viewers don't. Very useful when scrolling through thousand page datasheets.

This extension has a problem where it opens *local* PDFs that are opened from the bottom download bar in Chrome. Acrobat should be opening all local PDFs, seeing as how that's my default Windows application for the PDF file-type. "Allow access to file URLs" is already *unchecked*. Please fix this..
