Partial The UI and batch workflow are simple, but converting between JPEG, HEIC, AVIF, and JXL while preserving Ultra HDR gain maps and ISO 21496-1 metadata requires codec-level work. Off-the-shelf libraries help but handling gain-map metadata correctly is hard.
What it would actually take: Build an Android app that wraps native codec libraries (libavif, libjxl, libheif, and libultrahdr) and reads and writes gain-map metadata. The difficulty is correct color and HDR gain-map handling across formats, which requires imaging expertise and careful testing on real devices.
