I have now checked the latest Windows 11 2024 Update (Version 24H2), both x64 and Arm64 platforms, and found that there is finally support for JPEG with arithmetic coding (JPEG 7) in the system, but not in the Edge browser:
File Explorer Thumbnails View- Windows Photo Viewer
- GDI+ (checked with SimpleImage)
Edge browser
Good that there is finally some JPEG progress in Windows, albeit slowly.
Apple managed to use their own enhanced image functions with their Safari browser in macOS.
Microsoft seems not so smart, they use a vanilla browser engine with inferior image support.
