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

Thanks you so much! I feel better when see documents online than download and see offline. Good app!

Ich habe leider noch keine Einstellung gefunden, die ich durchführen könnte, damit Download-Links von PDF-Dateien nicht online geöffnet werden, was ich sehr ärgerlich finde.

pdf.js hits the sweet spot between leanness and features: chrome built-in viewer is too basic (no backward button!), while acrobat is clunky and bloated. Great to see it implemented in Chrome! One feature request: it would be great to be able to set a custom default zoom level.

the printing is always horrible. besides that the app is great. it would be nice if there was an option to quickly get a direct link. the link the app provides has the link embedded in a longer link and others without the app cannot open these. please fix that and printing, as it has the margins way off and usually only prints the left side of the document. if you open in adobe and print, it prints properly.

bookmarked files are saved as a chrome extension descriptor+the actual file url, which makes it unpleasant to use other readers.

It is a huge problem that without the premium version downloading a pdf file seems very hard to achieve. Otherwise it would be good but as long as it isn'T fixed I'm not going to use it. Feeling sorry for you.
