Overview

Product summary

Review the store description, core capabilities, and common use cases.

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, and all other readers based on PDF.js are surely better than the Chrome default in speed and offer more operational possibilities, but the chrome://xxxx prefix before the URLs is annoying, and it also prevents some other extensions (e.g. Zotero) to handle the PDFs. But I guess this can't be solved. Is it possible to introduce a "blacklist" mechanism so that this extension is not functional for specific sites?

The application is very good at what is says - to view PDFs. No bells and whistles but, given the name, that is to be expected. If highlighting/comment functionality was added, this would go to 5* easily.
