One thing that really stood out to me in the Safari 14 Release Notes was support for webp.
webp is a much more compact image format than PNG, but it offers a lot of the features we need from PNG such as transparency. Webp also has animation support, and is all around a much more advanced image format for the web than some of its predecessors. Safari was very slow to the game.
In most cases webp is also a better option than jpeg. Progressive jpeg, which offers more pleasant rendering options, may still be the right choice in some cases, but in general we may be done with the need to serve different formats to different browsers.
DEV renders webp to Chrome and Firefox, but not to Safari. We save terabytes of expensive bandwidth this way, but the complexity required to render different formats is something we'd be happy to do away with. So I am very happy about this.
Happy coding ❤️
