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

1. Needs an option to pick which folder the PDF downloads to. 2. Right-click/save as... only gives the option to download as a webpage.

Really useful! Don't know why Chrome doesn't have native inbuilt PDF viewer support, but this app is incredibly helpful for getting around that.

Doesn't seem like the header can be minimized? Otherwise great extension.
