AI overview

JPEG is a file format that compresses images to make them smaller and easier to store or share, with the ability to adjust how much quality you're willing to sacrifice for smaller file sizes. It matters because it's widely used for photographs and images on the internet, allowing people to balance image quality against practical storage and transmission needs.
