Convert JXL to HRZ

The JPEG XL (JXL) file extension, is a next-generation image format developed by the Joint Photographic Experts Group, combining Google's PIK and Cloudinary's FUIF formats. It supports both lossy and lossless compression, offering up to 60% better compression efficiency compared to traditional JPEG, while maintaining high image quality. Standardized in 2021, JPEG XL is designed for web delivery, professional photography, and digital printing, supporting ultra-high-resolution images, wide color gamuts, and advanced features like progressive decoding and multiple layers.

The HRZ file extension is associated with Slow Scan Television (SSTV), a method used by amateur radio operators to transmit still images via radio waves. HRZ files store images rendered from SSTV audio signals, typically as 256x240 pixel RGB bitmaps. These files can be viewed using software like XnViewMP or Logipole Konverter. SSTV allows for the transmission of images over high-frequency bands using single-sideband modulation (SSB). The HRZ format is not widely produced by specific programs, but several image viewers support it.
