The App Icon Generator is an essential tool for mobile developers. It streamlines the tedious process of creating the dozens of different icon sizes required for iOS and Android apps. Simply upload a single high-resolution image, and the tool will generate a complete set of icons for you. You can add padding, set a custom background color, and adjust the corner radius to perfectly match your app's design aesthetic.

1. Click the upload area to select a high-resolution, preferably square image (e.g., 1024x1024px).
2. Use the controls to adjust the icon's appearance:
   • Padding: Add space between your image and the edge of the icon.
   • Border Radius: Control the roundness of the icon's corners.
   • Background Color: Pick a color to fill the background, which is useful if your source image is transparent or has padding.
3. The tool will generate previews for all standard iOS and Android icon sizes.
4. Click the download button next to any icon to save it individually.
