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

Een prima extensie die zijn werk zeer goed doet. Ik gebruik het nu zo'n 3 maanden en heb nog problemen ondervonden. Openen, scrollen, zoomen alle bewerkingen worden goed uitgevoerd. Een boek van 488 pagina's afdrukken met aangepaste instellingen leverde geen problemen op. Thumbs Up For Me.

I like this because the default Chrome PDF viewer doesn't save your place, with this one I can read books and not worry about closing out of the tab or restarting my computer.

Added for the option to return to the page where I left off when reading a book, and it works perfectly.
