How do I convert ICO to DDS with this tool?

Upload your ICO file. Choose the DDS output format: uncompressed RGBA8 or BC7. Enable mipmap generation if needed, then click Convert. The tool selects the largest embedded image (usually 256×256) by default; you can pick another size from the detected list.

Why should I convert ICO to DDS instead of using PNG or ICO?

ICO is a Windows icon container primarily for UI, while DDS is a GPU texture format used by DirectX, Unity, Unreal, and Vulkan. DDS supports BC7 block compression to reduce VRAM usage and hardware mipmaps for better LOD transitions. Converting to DDS avoids runtime decoding of ICO and makes assets directly usable in game pipelines.

How does the conversion handle transparency, color depth, and multiple sizes?

The converter extracts the highest-resolution image from the ICO. If it uses PNG compression, 8-bit alpha is preserved exactly; if BMP-based, the 1-bit alpha mask is converted to 8-bit for smooth edges. For DDS, you can output uncompressed RGBA8 (lossless) or BC7 (high quality, smaller footprint). Mipmap generation can be enabled, but DPI and metadata from the ICO are not retained because DDS is a pixel-based texture format.
