Convert jxl to fits

What is the difference between .jxl and .fits?

Description: A JPEG XL file is an image saved in a compressed graphic format currently under development by the Joint Photographic Experts Group (JPEG). It supports wide color gamut and HDR (High Dynamic Range), alpha channels and animation frames while providing visually lossless compression. Images can be converted back and forth between JPEG XL and JPEG without loss of quality. Converting a regular JPEG to JPEG XL reduces the file size by 22%. JPEG XL files can be used to store any type of image content.; The Flexible Image Transport System (FITS) file format is a digital file format used primarily in astronomy for storing, transmitting, and analyzing scientific images and data. Developed in the late 1970s, FITS was designed to provide a standard for the interchange of astronomical data, facilitating the sharing and analysis of data among astronomers and researchers worldwide.
