JPEG XL is an image file format designed to improve upon traditional JPEG while ensuring compatibility across operating systems. It offers better compression and high-quality images at a smaller file size than standard JPEGs. Windows 11 doesn't support JPEG X image format by default, but you can install an add-on that does. Here's how to add JPEG XL support in Windows 11.
