Thanks Mateusz, I already studied the tutorial page, but the TYPE of the biggest part of the images of my woocommerce ecommerce is still jpg. Only the logo and few images related to themes are webpp.
How can I fix it?
Going into MEDIA, all the images of my woocommerce result modified and optimized. But by inspecting the page, I only see the logo and few other images converted in webpp.
