## AI vs ICO

|  | AI | ICO |
| --- | --- | --- |
| Full name | Adobe Illustrator Artwork | Windows Icon |
| Type | Vector | Image |
| Extensions | .ai | .ico |
| MIME type | application/illustrator | image/x-icon |
| Best for | editable vector artwork from Illustrator | favicons and Windows application icons |
| Properties | vector, proprietary | transparency |

**AI:** AI is Adobe Illustrator's native vector format. Modern AI files are PDF-compatible, which lets them be converted without Illustrator.

**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.
