Look here to learn how to enable JPEG XL:
JPEG XL is the next-generation image format that is poised to replace the currently existing formats such as JPEG (about 60% smaller with the same quality) , PNG, GIF, WebP and AVIF.
It supports transparency (alpha channel) and animation, as well as lossy and lossless modes, progressive decoding, wide gamut, HDR and much more, while being independent of any licenses.
At the moment it is implemented in all major browsers (Chrome, Firefox, Edge, Safari and Opera), although there are not yet many tools that can output this file format. Here you can test this image format of the future.
If you always wanted to know how the JPEG compression works under the hood I want to recommend this article to you. It was important to me to write an article that is reasonable for every level of understanding.
Furthermore it contains 7 valuable tricks to reduce the file size of your JPEGs by exploiting the technical functionality of the JPEG compression algorithm.
