+**Contributors:** [codeparrots](https://profiles.wordpress.org/codeparrots), [eherman24](https://profiles.wordpress.org/eherman24)  
+**Tags:** [c[webp](https://WordPress.org/plugins/tags/webp/)](https://WordPress.org/plugins/tags/cwebp/), webp, [image](https://WordPress.org/plugins/tags/image/), [compression](https://WordPress.org/plugins/tags/compression/)  
+**Requires at least:** 4.0  
+**Tested up to:** 4.9  
+**Stable tag:** 1.0.0  
+**License:** GPLv2 or later  
+**License URI:** http://www.gnu.org/licenses/gpl-2.0.html  
+
+Bye-bye third party services - automate the conversion of images in your media library to the `.webp` format (on your own server) and conditionally serve them to supported browsers on the front end.
+
+<strong>Note:</strong> `cwebp` must be installed on the server and readily available in the system `$PATH`, for this plugin to function correctly. This is not available on shared hosting.
+
+*cwebp Installation*
+
+MacOS:
+`$ brew install webp`
+
+Additional Installation Instructions:
+<a href="https://developers.google.com/speed/webp/download" target="_blank">Downloading and Installing WebP</a>
+
+<strong>Supported Image Types:</strong>
+* jpg, jpeg
+* png
+
+<h3>How Does This Work</h3>
+
+Anytime an image is uploaded through the media library a related .webp image is generated inside of a subdirectory in the uploads directory.
+
+**Example:** `wp-content/uploads/webp/`  
+
+On the front end of your site, if a `.webp` format is available for the media element than the `.webp` format will be served. If not, or if a browser doesn't support `.webp` formats - then the original image will be served to the browser.

+
+## Description ##
+
+1. Install cwebp - https://developers.google.com/speed/webp/docs/cwebp
+2. Upload and use media library as usual. When an image is uploaded a `.webp` image will be generated inside of the `wp-content/uploads/webp/` directory.
+3. If supported, the `.webp` image will be served to the browser, otherwise the original will be referenced.
