Description

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 Don't have a Github account? I also accept feedback at rob@robwu.nl Known issue: PDF files generated via a form (POST request) cannot be viewed. Contains opt-out telemetry since version 1.5.285, see https://github.com/Rob--W/pdfjs-telemetry#privacy-policy

#1 It has one of the dumbest implentation of editing a PDF -- if you Edit a pdf -- you will want to save it, does it? No, it downloads a version of it into your downloads directory. Who will use such a dumb way of doing things -- the file is edited, means a copy of it should go where file was - not in the default chrome downloads directory. #2 I couldn't get it to show me the hand tool -- and why is is buried? why not put it on the top toolbar -- you have grabbed the space on the top of the screen -- use it, rather than hide the features in a menu on the right #3 Print implentation is awful - it dumps landscape documents to portrait settings! I wanted to like it because it's edit is better than edge -- but even that is missind drawing a line straight line with an arrow -- that's about 90% of the reason of using an edit on PDF .. but ony offer is to draw squiggly lines -- what a shame

After closing and reopening Chrome and reopening last session (ctrl+shift+T), the PDF tabs are gone and become "new tabs".

i works good but it does not change pdf logo in file location as it change in edge browser which is convenient to identify the document where in chrome it just show chrome logo in pdf files, bad to use

Out of date. The latest PDF.js has newer features. This extension hasn't been updated since 2019!

We have been using this extension for QA automation testing using robot framework PDF doc verification, Currently I am unable to use it on Chrome 74.

Does absolutely nothing. PDFs still can't be associated with Chrome. I even set Chrome as the default application to open PDFs and all it does it move the file into the "download" folder... garbage.

Downloads unwanted "Better Tab." I don't like Kami which is why I tried this viewer. Am uninstalling it immediately due to spyware.

Irrecoverably loses all your open pdf tabs if the extension is disabled. Just what you need.
