Why convert JXR to ICO?
JXR is the JPEG XR image format, introduced by Microsoft as HD Photo and standardised for high-quality photographic storage with efficient compression. The photo is decoded with the JPEG XR reference decoder at its full width and height, keeping the picture exactly as it was framed.
ICO output is a 256 × 256 pixel Windows icon: the image is scaled to fit with its proportions kept, and the surrounding space is transparent.
