Drop an image and get an ICO with multiple sizes. Everything runs in your browser.
ICO files bundle multiple icon sizes into a single file. Browsers pick the best match for the context: 16px for tabs, 32px for bookmarks, larger for shortcuts and app icons.
Common sizes: 16, 32, and 48 for browser favicons. 64 and above for desktop shortcuts and high-DPI displays.
For best results, start with an SVG or a large PNG (512px+). Smaller sources may look blurry when scaled up.
The generated ICO uses embedded PNG data, which is supported by all modern browsers and Windows Vista+.
