 Yes, Safari 17 supports JPEG XL. On macOS Sonoma, macOS Ventura and macOS Monterey, as well as iOS, iPadOS, watchOS, and soon, visionOS. We also added HEIC — especially for web apps that want to let users edit photos directly from the camera. https://webkit.org/blog/14205/news-from-wwdc23-webkit-features-in-safari-17-beta/#images 8 comments
 @jensimmons "On macOS Sonoma you can pair with Apple TV and Vision Pro directly from Safari to inspect those platforms." Does this mean Safari is coming to tvOS? :o  @jensimmons not so stoked about HEIC support because of the licensing situation around it, which will prevent other WebKit ports from shipping it and cause web compat problems; but yay for JPEG-XL support and hoping Chromium and Firefox follow. We should probably enable by default the support in the GTK and WPE ports. On a related note, it would be good to get rid of JPEG2000 support, this ended up stagnating: https://github.com/WebKit/WebKit/pull/3824  @jensimmons Does this mean that Safari iOS will no longer convert HEIC to JPEG when picked by a input type=“file”? |

@jensimmons I'm curious to see if that pushes Firefox to back JPEG XL as well (and thus lead to a comeback in Chrome)
