ICO sizes

Why use ICO?

ICO files can contain several favicon sizes in one file and work well for browser tabs, desktop shortcuts and Windows apps.

Private conversion

Your image is not uploaded. The ICO file is generated directly in the browser using Canvas.

Recommended sizes

Use 16×16, 32×32, 48×48, 64×64, 128×128 and 256×256 for broad favicon support.
