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

Finalmente!!! I file PDF si possono finalmente aprire solo in lettura, Invece di scaricarli ogni volta. Non si capisce perché Chrome non ci abbia pensato

Should be the default in Chrome, just like it is in Firefox.

Excellent. Much better than the default chrome PDF viewer. I only wish it could open PDFs from Google Drive without having to download them first. Is this a planned feature?

Love it. Sometimes it needs the F5, but other than that it's great! :)
