You can embed PDFs in a WordPress blog and make it available for others to download as well. In this article, we will show you how you can embed PDFs, Microsoft Word Documents, PowerPoint slides, Excel Spreadsheets, and other elements in your WordPress blog by using a plugin called Google Doc Embedder. It does not require you to have a Google Docs account. It simply uses the Google Docs viewer to display all of those files on your blog.

What does the PDF Viewer plugin do? In WordPress if you install and activate the PDF Viewer your users will be able to view, search and even print pdf documents right inside your website without having to leave your website. By default WordPress does not embed PDF files into blog posts like it does with audio and video embeds. It just adds the file as a downloadable link. Clicking that link takes users away from your website which decreases the overall time they spend at your website.
Upon activation, you need to visit Settings » PDF Viewer to configure the plugin settings. PDF Viewer plugin allows you to control the height and width of the PDF viewer. You can change this. You can also disable support for older versions of Internet Explorer. By default, the plugin will not show the PDF viewer to users with Internet Explorer 9 or below. Instead, those users will see a download link. You can modify the message users with old browsers will see.
