webp images module

2.0.1 2023-10-03 08:53 UTC


This SilverStripe module generates webp images from resized jpeg and png images.


  • See composer.json requirements
  • GD with webp support


  • composer require wedevelopnl/silverstripe-webp-images

Next, you'll need to run a dev/build (or at least flush) to allow access to files with the .webp extension from the .htaccess in your assets directory.

Known issues

Using $Image.DisableWebP in a template

Putting $Image.DisableWebP in a template will not work, this somehow calls getUrl twice, properly disabling the webp URL generation on the first run, but actually outputting the second run after which the disabled flag will have been removed. A workaround for this is to use <img $Image.DisableWebP.AttributesHTML />
