<h3>Basic use</h3>
<p>To embed a PDF you’ve uploaded to your WordPress site’s media<br />
library, simply put the URL for the attachment page in your<br />
post on its own line. The PDF will be embedded with the<br />
default settings at that location, as if it were using oEmbed.</p>
<h4>Examples:</h4>
<pre><code>Post short URL:

http://www.example.com/?p=3

Attachment default URL:

http://www.example.com/?attachment_id=9

Attachment pretty URL:

http://www.example.com/test/report1/

Media direct URL:

<p><a href="http://www.example.com/wp-content/uploads/2013/11/report1.pdf" target="_blank" rel="noopener noreferrer nofollow ugc">Click to access report1.pdf</a></p>
</code></pre>
<p>This doesn’t work for PDFs hosted on other websites, or if you<br />
need to change the parameters.</p>
<h3>Using the <code>[pdf]</code> shorttag</h3>
<p>If the PDF isn’t in your WordPress site’s media library, or if<br />
you want to customize any parameters for the embed, then use<br />
the <code>[pdf]...[/pdf]</code> shorttag. Between the tags, you’ll provide<br />
the URL for the PDF to embed. If the PDF is in your WordPress<br />
site’s media library, you can either give the attachment page<br />
URL, or the URL to the PDF file directly.</p>
<p>The <code>[pdf]</code> shorttag accepts several optional parameters:</p>
<ul>
<li><code>width</code> – sets the width of the frame the PDF is embedded in.<br />
By default, this is set to 100%.</li>
<li><code>height</code> – sets the height of the frame the PDF is embedded<br />
in. By default, this is unset.</li>
<li><code>title</code> – sets the title of the PDF, for use in the fallback<br />
link text.</li>
</ul>
<h4>Examples:</h4>
<pre><code>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]
</code></pre>
<h3>Compatibility</h3>
<p>The PDF should be embedded in the page, with the document scaled so it fills the<br />
embed frame horizontally. Unfortunately, embedding PDFs is not well-supported.</p>
<h4>Auto-loading embedded PDFs</h4>
<p>Unlike with images, web browsers may not automatically download and display<br />
embedded PDFs when the page is loaded. For security reasons, some users prefer<br />
not to allow the PDF plugin to run unless they trust the website the PDF comes<br />
from. This generally leaves a grey rectangle that the user may click on to allow<br />
the PDF to be downloaded and displayed.</p>
<h4>PDF open parameters</h4>
<p>There is currently no way to customize the <a href="http://partners.adobe.com/public/developer/en/acrobat/PDFOpenParameters.pdf" rel="nofollow ugc">PDF open parameters</a>.</p>
<h4>Chrome</h4>
<p>The PDF should be scaled/zoomed within the embed frame so that the full<br />
horizontal width of the paper fills the frame. This is <a href="https://code.google.com/p/chromium/issues/detail?id=64309" rel="nofollow ugc">not<br />
supported</a> in<br />
Chrome’s default PDF viewer, so the document will probably be scaled to 100%,<br />
which may either mean the document doesn’t fill the frame, or, more likely, the<br />
document is too wide for the frame, and the right-hand side of the document is<br />
hidden.</p>
<h4>Internet Explorer</h4>
<p>Internet Explorer requires a PDF plugin to render embedded PDFs. Generally,<br />
that’s Adobe Reader. Without such a plugin, the fallback download link will be<br />
used.</p>
<h4>Mobile browsers</h4>
<p>In particular, mobile browsers may show a grey box instead of the embedded PDF,<br />
and will download the file when it is clicked. Other mobile browsers might embed<br />
the PDF, but won’t allow it to scroll.</p>
<h3>Alternatives</h3>
<p>Your best alternative is to <strong>not</strong> embed PDFs. PDFs are bad for many reasons:<br />
not easily indexed by search engines, not easily accessible by readers who use<br />
assistive technologies, poorly supported by web browsers (as seen above) and so<br />
on. They’re just <strong>bad</strong> and you should avoid embedding PDFs if you can.</p>
<p>If you <em>really</em> can’t, then you might consider using another solution like<br />

<p>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.</p>
<p>Inspired by <a href="https://wordpress.org/plugins/dirtysuds-embed-pdf/" rel="ugc">Embed PDF</a> and <a href="https://wordpress.org/plugins/rv-embed-pdf/" rel="ugc">RV Embed PDF</a>.</p>
<p>Many thanks to <a href="https://github.com/akirk" rel="nofollow ugc">Alex Kirk</a> for making Embed PDF Viewer compatible with the new block editor.</p>
<p>Development on <a href="https://github.com/afragen/embed-pdf-viewer" rel="nofollow ugc">GitHub</a>. Pull requests are welcome against the <code>develop</code> branch.</p>
<h3>Known Issues</h3>
<p>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.</p>


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!

Works out of the box

Fantastic
