WebP for Joomla!

WebP for Joomla!

  • Smaller images
  • Less bandwidth
  • Faster websites

WebP is an image format - developed by Google - aimed to reduce the size of images dramatically. While still in development, WebP images already allow you to reduce the size of JPG or PNG images. Use it in Joomla and you can save tons of bandwidth.

Getting started

  • Get WebP running in your hosting environment
  • Install the plugin in the Extension Manager
  • Enable the plugin in the Plugin Manager


  • Serve WebP images to WebP enabled browsers
  • Automatically convert any PNG or JPG into WebP
  • Make your website faster than ever


This extension integrates WebP into Joomla, and adds WebP images to the page if the browser supports it. Browser support for WebP is detected based on a simple user-agent check (so that Chrome browsers are matched right away) and an additional JavaScript detection (so that other WebP browsers are matched as well). If WebP is detected, the extension will parse the HTML output to make sure links to supported images (png, jpg, jpeg) are actually replaced with WebP images.

Note that you will need to install the WebP binaries on the webserver. If you don't have root access or shell-access, you probably need to ask your system administrator to install WebP for you. If you need our help with this, drop us a mail.


You can see a demo of the WebP extension for Joomla by visiting the Yireo demo site http://joomla1.yireo-demo.com/ with a WebP-enabled browser. Currently the Chrome browser supports WebP out of the box, while for Firefox there is a WebP plugin available.
