A JXL file uses JPEG XL, a modern image format designed to replace JPEG. It delivers much smaller file sizes while keeping high visual quality. JXL supports lossy and lossless compression, HDR, wide color gamut, alpha transparency, and even progressive loading.
JPEG XL can also re-encode existing JPEGs without quality loss, making it ideal for next-generation web images and long-term photo storage.
JXL files are commonly used for:
High-quality web images
Image archiving and storage
Photography and design
HDR and wide-color images
JXL files can be opened with:
Google Chrome (with support enabled)
Firefox (experimental support)
GIMP
XnView MP
ImageMagick
