## Good to know

- DDS doesn't support transparency, so transparent areas are filled with white.

- This conversion runs on ImageMagick, running locally in your browser — nothing is uploaded and it works even on slow connections.

## ICO vs DDS

|  | ICO | DDS |
| --- | --- | --- |
| Full name | Windows Icon | DirectDraw Surface |
| Type | Image | Image |
| Extensions | .ico | .dds |
| MIME type | image/x-icon | image/vnd-ms.dds |
| Best for | favicons and Windows application icons | textures for games and real-time 3D |
| Properties | transparency | lossy compression |

**ICO:** ICO is the Windows icon format. A single ICO can hold several sizes of the same icon, which is why it's still used for website favicons.

**DDS:** DDS stores GPU-compressed textures with mipmaps so games can load them directly into video memory.
