Convert jfif to jxl

What is the difference between .jfif and .jxl?

Description: The JFIF (JPEG File Interchange Format) format makes it possible to transfer compressed JPEG files across computers. This graphical file format uses a marker to show various parameters not seen in the standard JPEG file — for instance, pixel size, pixel geometry, among others.; 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.
