Why convert JXR to WebP?
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.
WebP stores the rendered image in a modern, efficient format, so the file is noticeably smaller than an equivalent PNG or JPG.
