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".

Great tool! Everything I need, including that extension remembers the last page I were reading before closing the document...

Very Very useful extension! The default built in PDF viewer sucks! This extension even better than the built one! more smooth, more efficient! It allows Chrome to opens PDF urls automatically.

So, my 5-star review is because after spending almost 2 hours hassling with 3 different options, I found out that this extension, allows me to add text to a pdf file, I can change the color and size of the font - not the font itself but hey, it's free. I am in love with this extension now and highly recommend it for adding text. Hope this helps others decide.

Great extension, much more convenient than built-in PDF viewer, just one feature request: Please make it possible to open a PDF in the built-in viewer anyway. Just for compatibility reasons. For example, I cannot use other extensions for summarizing the PDF etc. when viewing the PDF in this extension (extensions are not allowed to work on other extensions' pages). Otherwise great!
