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

Great! I am using the Chromium so the default Chrome PDF viewer is unavailable to me. This is a nice replacement.

No problem for viewing, however impression is of low quality, if I save & open the pdf in an external pdf reader it prints in an excellent quality Aucun souci pour la visualisation, en revanche l'impression est de faible qualité, si j'ouvre le même pdf dans un lecteur pdf externe il s'imprime en excellente qualité... dommage

Best PDF viewer on the chrome store. However, font's look horrible. I was going to return my Chromebook because of the lack of PDF support. Then I found this extension, so I second guessed returning the Chromebook. But the typeface is so bad, mixed with removing backgrounds from PDFs, I decided to still return my Chromebook. Overall bad experience.

Finally found a long-awaited alternative over Chrome's PDF viewer, and it has lived up to my expectations. :)
