The Chrome, Edge, Brave, and Opera web browsers all properly display such images. While all of those browsers are a suitable workaround on MacOS (instead of Safari), they are all dependent upon WebKit for browsing on iOS / iPadOS. Therefore, it is not possible to properly view HDR photos on Apple iPhone / iPad, which is unfortunate as Apple has some of the best hardware out there. 1998672 1 webkit-bug-importer 2023-12-11 09:09:16 -0800 <rdar://problem/119496932> 2107009 2 sabouhallawa 2025-03-28 17:36:51 -0700 This should be working in WebKit if you enable the "Support HDR Display" feature.
