Embed PDFs straight into your posts and pages, with intelligent resizing of width and height. No third-party services or iframes required. 

== Description ==

Upload PDFs and embed them straight into your site - just like adding images! PDFs will be automatically sized to their natural size and shape (or just fill the width available if they are too big). Optionally, you can specify a width and the correct height will be calculated automatically. The shape will be recalculated whenever the page is resized by the user.

The plugin has a unique method for embedding PDFs, using Javascript only, and _not_ using iframes or third-party services. This gives a lot of flexibility over the appearance of your document.

The viewer currently has Next/Prev buttons to page through the document, and zoom buttons. There is no button to download the entire PDF (but of course a savvy user will be able to obtain the content since it is displayed to them).

It uses a customized version of Mozilla's PDF.js project, but embeds it within your existing WordPress pages so we have full control over appearance. Other plugins may use similar technology, but they will insert the PDF itself into an 'iframe' which means they do not get the flexibility over sizing.

= Usage =

Once installed and Activated, click Add Media from any page or post, just like adding an image, but drag and drop a PDF file instead.

When you insert into your post, it will appear in the editor as a 'shortcode' as follows:

[pdf-embedder url="https://mysite.com/wp-content/uploads/2015/01/Plan-Summary.pdf"]

You can change the default appearance - e.g. width, and toolbar position/appearance through **Settings -> PDF Embedder**.

To override your site-wide defaults on an individual embed, see the [Plugin Instructions](http://wp-pdf.com/free-instructions/?utm_source=PDF%20Readme%20Instructions&utm_medium=freemium&utm_campaign=Freemium) for information about sizing options plus other ways to customize the shortcodes.

= Mobile-friendly embedding using PDF Embedder Premium =

The free version of the plugin should work on most mobile browsers, but it will be cumbersome for users with small screens - it is difficult to position the document entirely within the screen, and your users' fingers may catch the entire browser page when they're trying only to move about the document...

Our **PDF Embedder Premium** plugin solves this problem with an intelligent 'full screen' mode. 
When the document is smaller than a certain width, the document displays only as a 'thumbnail' with a large 'View in Full Screen' button for the user to click when they want to study your document. 
This opens up the document so it has the full focus of the mobile browser, and the user can move about the document without hitting other parts of the web page by mistake. Click Exit to return to the regular web page.

= Protect your PDFs with our secure premium version =

Our **PDF Embedder Premium Secure** plugin provides the same simple but elegant viewer as the premium version, with the added protection that it is difficult for users to 
download or print the original PDF document.

This means that your PDF is unlikely to be shared outside your site where you have no control over who views, prints, or shares it.

== Screenshots ==

1. Uploaded PDF is displayed within your page/post at the correct size to fit. 
2. User hovers over document to see Next/Prev page butons.

== Frequently Asked Questions ==

= How can I obtain support for this product? =

Please feel free to email [contact@wp-pdf.com](mailto:contact@wp-pdf.com) with any questions.

Always include your full shortcode, plus links to the relevant pages, and screenshots if they would be helpful too. 

We may occasionally be able to respond to support queries posted on the 'Support' forum here on the wordpress.org
plugin page, but we recommend sending us an email instead if possible.

= How can I change the Size or customize the Toolbar? =

See Settings -> PDF Embedder in your WordPress admin to change site-wide defaults. You can also override individual embeds by modifying the shortcode.

Resizing works as follows:

* If width='max' the width will take as much space as possible within its parent container (e.g. column within your page).
* If width is a number (e.g. width='500') then it will display at that number of pixels wide.

*In all cases, if the parent container is narrower than the width calculated above, then the document width will be reduced to the size of the container.*

The height will be calculated so that the document fits naturally, given the width already calculated.

The Next/Prev toolbar can appear at the top or bottom of the document (or both), and it can either appear only when the user hovers over the document or it can be fixed at all times.

See the [Plugin Instructions](http://wp-pdf.com/free-instructions/?utm_source=PDF%20Readme%20FAQ&utm_medium=freemium&utm_campaign=Freemium) for more details about sizing and toolbar options.

= Can I improve the viewing experience for mobile users? =

Yes, our **PDF Embedder Premium** plugin has an intelligent 'full screen' mode. 
When the document is smaller than a certain width, the document displays only as a 'thumbnail' with a large 'View in Full Screen' button for the user to click when they want to study your document. 
This opens up the document so it has the full focus of the mobile browser, and the user can move about the document without hitting other parts of the web page by mistake. 
Click Exit to return to the regular web page.

= Can I protect my PDFs so they are difficult for viewers to download directly? =

Not with the free or (regular) premium versions - it is relatively easy to find the link to download the file directly.

A **secure premium** version is available that encrypts the PDF during transmission, so it is difficult for a casual user to save or print the file for use outside your site.
