Incorporate Mozilla’s PDF.js viewer into your pages and posts with a simple shortcode. PDF.js is a javascript library for displaying pdf pages within browsers.


  • Elegant speckled gray theme
  • Customizable buttons
  • Page navigation drawer
  • Advanced search functionality
  • Language support for all languages
  • Protected PDF password entry
  • Loading bar & displays partially loaded PDF (great for huge PDFs!)
  • Document outline

Shortcode Syntax:

[pdfjs-viewer url=http://www.website.com/test.pdf viewer_width=600px viewer_height=700px fullscreen=true download=true print=true]
  • url (required): direct url to pdf file
  • viewer_width (optional): width of the viewer (default: 100%)

This plugin does not support a button within the Gutenberg interface, however the shortcode still works fine.

I tried about 10 viewer plugins and I can guarantee this is the best one! If the file is about 300kb or more all of the viewers load a blank white page, but this one waits and loads the pdf file. Also it has all features wich rest of the viewers has as premium features. Thank you!

The pdf.js plugin works perfectly in WordPess 4.9.8. The only thing I had to do in order to customize it was to edit the file pdfjs-viewer.php and on line 64 add a class and a target. $fullscreen_link = '<a href="'.$final_url.'" class="pdf-full-link" target="_blank">View Fullscreen</a><br>';

works as it says. a recent wordpress update (or something) had changed urls, but i see this as a wordpress issue and not something this plugin was doing. this plugin works, but has not been updated for close to a year. i have no current problems with it. if you have any problems, try checking your url string to make sure it's readable and that any symbols haven't been tweaked.

I have a few users who have a problem with their anti virus (Bull Guard) blocking this plug in. However, I have tested it successfully with IE, Chrome and Mozilla.
