Overview of new JPEG XL image standard - designed with responsive web design in mind, so that content renders well on a wide range of devices

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. It is designed with responsive web design in mind, so that content renders well on a wide range of devices. The JPEG XL coding tools include variable-size DCT, nonlinear Haar transforms, multiresolution encoding, adaptive quantization, adaptive loop filters and context modeling.

JPEG XL is also designed to meet the needs of high-quality imaging and professional photography. A color-managed processing pipeline with full 32 bit per channel precision enables support for wide-color-gamut/high-dynamic-range images. JPEG XL reaches high compression efficiency at visually lossless quality (as defined in ISO/IEC 29170-2) using psychovisual modeling plugins.

JPEG XL further includes features such as animations, alpha channels, lossless and progressive coding to support a wide range of use cases including but not limited to photo galleries, e-commerce, social media, user interfaces and cloud storage.

Looks like it will be very versatile and allowance has also been made for some transitioning from legacy standards so that everything does not break. There is more detail at #^https://jpeg.org/jpegxl/.
