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 extension significantly reduced the time it took to preview large PDFs.

Good extension. Works great and doesn't get in the way. There are times when a PDF link can't be opened by the extension for whatever reason (it says the file is corrupted). If I then turn off pdf.js, and then click the same link, I download the PDF and I view it just fine. I then turn pdf.js on again. As you understand, this process of 'disable pdf.js, download PDF, enable pdf.js' is very time consuming. It'd be great if there was an easy way to override the extension for those occasions and just let us download the PDF *asif* the extension wasn't present; it'd be great if we could do that anyway for the PDF's we know we want to download anyway. Thanks for a great service.

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.

НАКОНЕЦ ПЕРЕВОД В PDF Делает возможным работу других плагинов в хроме, что позволяет очень удобно читать книгу на английском с использованием любого плагина для перевода слов по клику, выделению и тд.

Better than in the built-in viewer of Chrome, and one of the best pdf viewer.
