Correctly sizing photos for desktop, tablet, and mobile devices is another effective way to speed up the loading time on a website.
Another method for faster image delivery is to use responsive images. Optimizing images for the size of the user's screen keeps them responsive.
Image formats like AVIF and WebP are the best for website speed. Both of them offer better compression over conventional PNG or JPEG.
Instead of loading every image in the user's viewport, lazy loading loads just the ones that are actually needed.
