XnView Software

- A lot of cameras save .heic so it would be cool to have one click fix whenever the orientation sensor of camera has made a mistake (which does happen)

- avif probably next in priority as it is already becoming common in internet
- and jxl after that although not yet common it is AFAIK most advanced of these formats.

If the jxl was transcoded from an original jpg and the reconstruction is present, you can do jxl => jpg => rotate|flip => jxl.

This could be checked & automated by XnView or a script - I don't know if the native jpeg-xl tools will have this capability in the future (like jxltran.exe similar to jpegtran.exe) or if lossless rotation|flipping of native jxl is possible at all - you could add a request to their guthub page or ask on their discord.
