Convert mat to jxl

What is the difference between .mat and .jxl?

Description: MAT (MATLAB Image Format) is an image file format created by MathWorks for storing and sharing MATLAB data and images. It contains data in a binary format, as well as metadata describing the image. MAT files can be used to store images, 3D models, and other types of data.; 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.
