Why Use I Love Sprites?

Preparing app icons for submission is tedious. Apple requires 18+ sizes, Android needs density-specific drawables, and web apps need favicons, touch icons, and Open Graph images.

Icons are organized into platform-specific folders and downloaded as a ZIP, ready to drop into Xcode, Android Studio, or your web project.

Frequently Asked Questions

Common questions about app icon generator.

1024×1024 pixels is recommended. The App Store requires this size, and all smaller icons will be scaled down from it.

Yes, but icons are square by definition. Non-square images will be stretched to fit. We recommend cropping to a square first.

All icons are exported as PNG, which is the required format for all app stores.

No. All processing happens in your browser. Your images never leave your device.
