What changes when you convert JXR to FITS

JXR can carry an alpha channel and FITS cannot. Transparent areas are composited onto a solid background during conversion, so pick that background colour deliberately: white is the default, and it is rarely the right choice for a logo that will sit on a dark page. FITS is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that JXR compression already removed, and the output file will usually be considerably larger.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression.
