I have received an ask about these formats via an email.

Created this Issue to gather more context on how people use rclip with these formats.

@yurijmikhalevich I would also gently propose adding support for JXL (JPEG XL). This format allows reducing the image library size a lot, while preserving the quality of original / source JPEG photos. It becomes more and more popular, especially since Apple started to use it as the default format for photos captured on iPhone 16 (2024) and newer.

2. https://github.com/libjxl/libjxl (reference implementation)
3. https://pypi.org/project/pillow-jxl-plugin/ (plugin for PIL/Pillow)
