About ICO

Windows Icon

The Windows icon format, which packs several sizes of the same image, such as 16x16 and 32x32 pixels, into one file. Each size is stored as a bitmap or a PNG. Convert to ICO to make a favicon or a Windows application icon.

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.
