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

great extension, I've been using it for more than 1 year and it's now essential to me. Better than any free pdf reader around

Love it! I would appreciate an update to update the underlying PDF.js library, though ;)

chromeでPDFを開くと埋め込まれてない日本語フォントが尽く江戸勘亭流で表示され非常に見づらかったのですが、ゴシックっぽい文字で表示できるようになって非常に助かっています!

Funciona correctamente y es mas completo que el visor de PDFs de chrome, recomendable. Solo hecho en falta poder ver los datos de firma cuando son pdfs firmados

Best for reading books, if you add highlighting option for making notes it will be much helpful.

Has been using for many years. After reinstalling Google, I understood how valuable it was.. Google's default PDF viewer is fine, but this is much faster and also has many features. Just a advice, please add a feature for highlighting texts.
