All about images on the web: current formats, how browsers load images, and upcoming formats – when and how to use them. This talk will start with a review of image formats commonly used on the web today – jpeg, git, png, SVG, and webp. What are they each good for? When and how should sites use them? Next, we will dig into the surprisingly complicated loading process of pages and images in the browser and the implications for site optimization. Finally, we will dive into newer formats like AVIF, JPEG XL, and WebP2, learn what promise they hold and how site owners can start using them today.
