Product summary

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

PDF.js is a awesome javascript tool that renders PDF files in Firefox. This extension brings this awesomeness to Chrome/ium. Thanks for making this, RobW!

Executa o pdf na aba o Chrome, como eu desejava e com possibilidade de download. Não executa arquivos de áudio e vídeo inseridos no pdf, como no EZ-Pdf reader para celular.

Couldn't read pdfs consistently with google's default program or adobe - This let me view them. Simple enough.

It works! However, no matter what display option you have set for your PDF files, this plugin will open a new window/tab and show it there. That's fine by me.
