JPEG XL (JXL) image format

A modern image format optimized for web environments. JPEG XL (also known as JXL) generally has better compression than WebP, JPEG, PNG and GIF and is designed to supersede them. JPEG XL competes with AVIF which has similar compression quality but fewer features overall.

Usage: 0% + 14.6% = 14.6%
