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".

Awesome and usefull extension. 2 suggestions. 1) an option to scoll by using mouse and keyboard. (now the ctrl+mouse wheel scales the entire page) 2) In presentation mode, animate the proces to go to the next slide (so a nice scroll animation).

デフォルトのフォントの指定ができれば嬉しいかな。Notoフォント使いたい。というかブラウザのフォント設定使って欲しい。MS明朝が使われているのか、アンチエイリアスが効いてないビットマップフォントで表示されるやつがある。美しくない。 あと、縦書きPDFで「」や──が回転せず横書き用のまま表示されてしまうのが残念。
