Embeds a PDF in your page or post when you insert it with the Add Media button.
I advise to not use this plugin for PDF because of the Google's limit.
You will get this error:
"You've reached the bandwidth limit for viewing or downloading files that aren't in Google Docs format. Please try again later."
The limit is so low that this happened even with Maintenance mode enabled. I reviewed the post a few times when formatting the article and got the error. This makes me sad because the plugin is otherwise well done and it's not the author's fault. We have to find another method to show PDF files without using Google Docs.
Summary: I had only one PDF, in one post, viewed only by me, and it stopped working. For info: the size of PDF I used is 400kb.
