There are a couple of different image optimization tools out there. Some batch compresses your images to a number of different set file sizes. We don’t. Instead we look at what viewport size a user has and generate optimized images to them on the fly. This also means you can change compression quality at any time, and that as soon as Avif (or a even better image format) is supported we can switch to it.
Some use CDN some don’t. We do. And if you use Elementor, you should definitely give us a try.
