Embed a PDF from the Media Library or elsewhere via oEmbed or as a block into an <code>iframe</code> tag. The URL only has to be world reachable link. Chrome uses Google Doc Viewer as Chrome seems to automatically rendered embedded JS in PDFs automatically. Uses Google Doc Viewer with mobile.

<h3>Known Issues</h3>
Occasionally Google Doc Viewer will not correctly load the PDF. Reloading the page should correct the issue, though this may need to be done several times.

Embed PDF Viewer

No settings, just add the link of the PDF on a page or use a block.

Had issue with the viewer width, but there's a simple solution for that as well, check this thread.

Thanks!
