Frequently asked questions
What size should my source icon be?
1024x1024 pixels is ideal. That is the largest size required by the App Store, and all smaller sizes scale down cleanly from it. You can upload any size, but starting smaller than 1024x1024 means some outputs will be upscaled and may look blurry.
Does this tool upload my icon anywhere?
No. Everything runs in your browser. Your image never leaves your device. We do not store, transmit, or process your icon on any server.
Can I use a JPEG or SVG instead of PNG?
Yes. The tool accepts PNG, JPEG, WebP, and SVG. All outputs are exported as PNG, which is what the App Store and Google Play require.
Do I need to add corner radius to my iOS icon?
No. Apple applies the rounded corners automatically. Upload a square icon with no rounding, and iOS will mask it to the correct shape.
What about Android adaptive icons?
This tool generates the standard ic_launcher.png files for each density bucket. If your app uses adaptive icons (foreground + background layers), you will still need to set those up in Android Studio separately. The generated files work as the legacy fallback.
Need app store screenshots too?
