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

Update: Excellent extension, works well as intended. Previous comment stated that it was not asking me where to save Downloads - this is confirmed to be a Chrome bug. Thanks, Google, for breaking something that was working fine.

The viewer itself works fine. I am docking 2 stars because everytime I open a pdf in chrome it gives me this weird address "chrome-extension://oemmndcbldboiebfnladdacbdfmadadm" in the address bar. I don't like it as I try to copy and past from the address bar to send links in emails and this messes up the link.

PDF Viewer apre i PDF direttamente in una nuova tab di Chrome e li renderizza perfettamente. Lo stile del plugin in se ( ovvero i comandi come lo zoom, cambio pagina tramite la piccola text field, anteprima stampa, eccetera...) è praticamente uguale al plugin bult-in PDF di Firefox. Non posso chiedere di meglio. 5/5
