FAQ
HDR to ICO Conversion
What are HDR files?
The HDR file format (.hdr) is a raster image format designed to store high dynamic range (HDR) data, capturing a wider range of brightness levels than standard formats like JPEG or PNG. Developed by Radiance, it uses a 32-bit floating-point representation per channel, enabling realistic lighting, shadows, and highlights.
What are ICO files?
ICO files contain the images used as icons for files, folders or programs on the Microsoft Windows platform. The icons appear on the desktop, in Windows Explorer or in the Start Menu and help identify each item. ICO images are generally of a small size, are scalable, and they can also serve as website logos or symbols that appear in the web browser next to the URL. The equivalent of ICO files on Mac computers is called ICNS.
