I've said it before... do you know ImageOptim?

An app, available for Mac that allows us to squeeze images in a not-very-fast* but very effective way

* The algorithm uses several codecs to get the best optimization & max quality (Best tool column)

Use media to define a media query to load a responsive image

The browser loads the `image.jpg` in the mobiles version, the `image-wide.jpg` in tablets resolutions or bigger, and the `image-ultrawide.jpg` will be loaded in screen resolutions bigger than 1200px

Web Performance Tip: add the attribute loading="lazy" to all images below the fold to delegate the lazy load function to the browser.

In this case, I added it to all images for mobile devices to avoid download more than 15MB πŸ™ˆ
