WebP is a newer file format for images to be used on the web. By using the WebP image format, your images will be 25-34% smaller in file size than PNG and JPEG without losing quality.
Some plugins are free but they demand active API to convert all images indide a media folder.
As they perform active API and rewrite Apache rule it is an issue how to do this inside cPanel as it supports NGINX where htaccess rewrite rule does not have an effect.
Can be managed without a plugin in the case of NGINX and cPanel?
