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

比chrome自带的pdf浏览器好多了: 1.带目录 2.自动记住上次打开位置 3.可以直接跳转到某一页

Great, just being able to view local PDF files and have them open where they were last viewed is a godsend for me. I was fed up with the default viewer opening at the start every time and not saving last viewed page position. This, at times, ended up needing to manually scroll 500+ pages to get to where I previously was in a book or manual, which was a major PITA, but not any more, thank you!

For those who love Mozilla Firefox' PDF viewer. Just great! (It's the official pdf.js viewer maintained by Mozilla)
