There is this JPEG XL art gallery with very nice images 20-100 bytes e.g.: https://jpegxl.info/art/2021-04_jon.html
To see them, enable flag in chrome: chrome://flags/#enable-jxl

Arithmetic coding encodes into range, ANS into single natural number.

"The JPEG XL Image Coding System (ISO/IEC 18181) has a richer feature set than existing codecs and can deliver images with similar quality at a third of the size of widely used alternatives."
Its lossy part is being developed by Google PIK team ( https://github.com/google/pik ) + Jon Sneyers (author of FLIF) – some details: https://encode.ru/threads/3108-Google-s-compression-proje%D1... https://encode.ru/threads/2793-PIK-image-format
