Convert pgx to jxl

What is the difference between .pgx and .jxl?

Description: The PGX file format is associated with Hopedot VOS, a virtual operating system software that allows users to run a separate operating environment on their computers, similar to virtualization technologies. A PGX file typically contains data related to the Hopedot VOS environment, such as settings, applications, and other user-specific information.; 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.
