Make the images the size they need to be for the space and in the format they need to be. Animated SVG? Use SVG. Photo use JPG. Art heavy vector? Use PNG.
I use optimisation software on all my sites via Imigify. But I put the right image and type where it needs to go in the right size first. Other people here suggest other optimisation plugins. Have a search for it you will get some good answers.
