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

Very practical extension with many more functions than the default one. I also set Chrome as default PDF app, so all PDFs are opened with PDF Viewer.

The best feature is not needing to download every PDF I want to open.

Doesn't open my file if its directory has some spaces (e.g., C:\Users\A(space)B\Documents\C(space)D.pdf). Please fix this ASAP!
