Frequently Asked Questions
What image format should I upload?
Upload a PNG or JPG file with a square aspect ratio (1:1) and at least 1024x1024 pixels. The image should have a solid or transparent background with your logo/icon centered. Avoid using photos as app icons - simple vector-style graphics work best.
Does iOS add rounded corners automatically?
Yes. iOS automatically applies rounded corners and the "squircle" shape to your app icons. You should upload a square image without rounded corners. The system will mask it appropriately on the device.
What's the difference between iOS and Android icons?
iOS uses a consistent grid system with specific @2x and @3x scales for different device pixel densities. Android uses density buckets (mdpi, hdpi, xhdpi, etc.) with different base sizes. Android also supports adaptive icons that can have different shapes on different devices.
Are my images stored on your servers?
No. All processing happens entirely in your browser using HTML5 Canvas. Your app icon designs are never uploaded to any server, ensuring complete privacy and security for your intellectual property.
