About AVIF
AV1 Image File Format
An image format from the Alliance for Open Media, finalized in 2019, that stores AV1-compressed images in a HEIF container. It supports lossy and lossless compression, alpha and HDR, and its files are often smaller than WebP. Use it for web images when you want the smallest files; current Chrome, Firefox and Safari all display it.
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.
