Embeds PDFs in your pages and posts, without using JS.
To embed a PDF you've uploaded to your WordPress site's media library, simply put the URL for the attachment page in your post on its own line. The PDF will be embedded with the default settings at that location, as if it were using oEmbed.
Post short URL: http://localhost/?p=9 Attachment default URL: http://localhost/?attachment_id=9 Attachment pretty URL: http://localhost/test/report1/ Media direct URL: http://localhost/wp-content/uploads/2013/11/report1.pdf
This doesn't work for PDFs hosted on other websites, or if you need to change the parameters.
If the PDF isn't in your WordPress site's media library, or if
you want to customize any parameters for the embed, then use
[pdf]...[/pdf] shorttag. Between the tags, you'll provide
the URL for the PDF to embed. If the PDF is in your WordPress
site's media library, you can either give the attachment page
URL, or the URL to the PDF file directly.
[pdf] shorttag accepts several optional parameters:
width- sets the width of the frame the PDF is embedded in. By default, this is set to 100%.
height- sets the height of the frame the PDF is embedded in. By default, this is unset.
title- sets the title of the PDF, for use in the fallback link text.
Post short URL: [pdf width="200px"]http://localhost/?p=9[/pdf] Attachment default URL: [pdf height="500em"]http://localhost/?attachment_id=9[/pdf] Attachment pretty URL: [pdf title="Report 1"]http://localhost/test/report1/[/pdf] Media direct URL: [pdf]http://localhost/wp-content/uploads/2013/11/report1.pdf[/pdf]
The PDF should be embedded in the page, with the document scaled so it fills the embed frame horizontally. Unfortunately, embedding PDFs is not well-supported.
Unlike with images, web browsers may not automatically download and display embedded PDFs when the page is loaded. For security reasons, some users prefer not to allow the PDF plugin to run unless they trust the website the PDF comes from. This generally leaves a grey rectangle that the user may click on to allow the PDF to be downloaded and displayed.
There is currently no way to customize the PDF open parameters.
The PDF should be scaled/zoomed within the embed frame so that the full horizontal width of the paper fills the frame. This is not supported in Chrome's default PDF viewer, so the document will probably be scaled to 100%, which may either mean the document doesn't fill the frame, or, more likely, the document is too wide for the frame, and the right-hand side of the document is hidden.
Internet Explorer requires a PDF plugin to render embedded PDFs. Generally, that's Adobe Reader. Without such a plugin, the fallback download link will be used.
In particular, mobile browsers may show a grey box instead of the embedded PDF, and will download the file when it is clicked. Other mobile browsers might embed the PDF, but won't allow it to scroll.
Your best alternative is to not embed PDFs. PDFs are bad for many reasons: not easily indexed by search engines, not easily accessible by readers who use assistive technologies, poorly supported by web browsers (as seen above) and so on. They're just bad and you should avoid embedding PDFs if you can.
