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

Opens PDFs in browser without having to download them first. Exactly what I wanted. I swear this used to be a native feature in chrome, but lately chrome has been requiring me to download the PDF first before opening it in a new tab—and this isn't an issue with my settings, I have the setting: "Download PDF files instead of automatically opening them in Chrome" turned off. Basically, this extension does what chrome used to.

Does not have access to files. I provided access in extension settings, restarted the browser, and even turned my tablet off and back on again. Running Win10. Thankfully I opened a PDF from the internet and realized it is working there otherwise I would have posted a very negative review.

Excellent extension! A little suggestion that the document outline in sidebar could keep folding by defaut, or else a document has hundereds outlines might make the reader very uncomfortable if the reader try to find a specified outline. Appreciate it!

Da mittlerweile kein Browser außer dem IE11 das Plugin vom original Adobe Reader unterstützt ist dieses Plugin für uns das Wichtigste überhaupt. Sämtliche integrierten PDF Viewer zeigen keine Anlagen innerhalb von PDFs an. Nur dieses hier. Vielen Dank dafür.

An extension that REALLY WORKS (many others that claim to do the same in fact they don't ....)! Would give 5 stars if full page scrolling (one single page at a time) with mouse wheel was enabled.
