About HDR

Radiance HDR

The HDR format from the Radiance renderer, storing each pixel as red, green and blue values with a shared exponent byte, so it holds a far wider brightness range than 8-bit images. Most HDRI environment maps ship in this format. Use it to light 3D scenes, or convert from it to get an ordinary 8-bit preview.

About JXL

JPEG XL

An image format standardized as ISO/IEC 18181 in 2022, with lossy and lossless modes, HDR and alpha. It can repack an existing JPG losslessly into a file about 20 percent smaller. Use it for archiving photos or for apps that support it; browser support is limited, so check before using it on the web.
