Image Converter for WebP Reviews
great plugin!
It does its job perfectly! The best thing is that the image is converted on demand when the user visits the page or post (and also the WooCommerce product), so there’s no need to run the server at 100
works where so many others fail
Works as advertised. I would love to see a scaling capability, however, for images over a user-specified width. I love the ability to auto-generate webp on-demand on user-view of the image!
