If you receive a message saying “No WebP conversion tools are available on your web-server”, instead of a checkbox option to enable WebP conversion, there are two possible explanations:
- PHP extensions such as ‘gd’, ‘imagemagick’, ‘imagick’, ‘graphicsmagick’, ‘gmagick’, ‘vips’, ‘ffmpeg’, ‘wpc’, ‘ewww’ are not installed on your server. Please ask your hosting provider to install one or more of these, so you can use the WebP conversion feature.
- Your hosting provider may have disabled shell functions such as escapeshellarg, exec, shell_exec, etc. Again, please ask your hosting provider to install one or more of the above in order to use the WebP conversion feature.
