PDF Shortcodes Ultimate

This plugin adds the “PDF” shortcode to the list of shortcodes provided by the Shortcodes Ultimate plugin, under the Media category.

It will let you select a PDF document from your Media manager (or directly enter an URL).

This shortcode, once inserted to your page or article, will render the PDF directly in your page (responsive, 16:9 aspect ratio).
In case the browser does not have a built-in PDF viewer, it will display the fallback link to download the PDF instead.
