How to Generate App Icons with AI (6 Models Compared)

Designing an app icon traditionally requires a designer with experience in icon-specific constraints — small size, instant recognition, simple shapes. AI generation makes it possible to create professional-looking app icons in minutes.

Available Models

ImgGPT's App Icon Generator offers six models:

Kontext Dev-Fast — 4 Credits

Quick iterations. Good for exploring many concepts rapidly. Quality is sufficient for evaluation but may not be final-output ready.

Kontext Dev — 5 Credits

Better quality than Dev-Fast. Good balance of speed and refinement for the exploration phase.

Kontext Pro — 8 Credits (Recommended)

The recommended model for most icon work. Produces high-quality icons with clean lines, good color rendering, and professional polish.

Kontext Max — 15 Credits

Maximum quality for final deliverables. Use when the icon will be scrutinized closely or needs to represent a premium product.

Seedream 4 — 6 Credits

Brings an aesthetic sensibility to icon design. Good for icons that should feel artistic or premium. Less precise control over exact design elements but beautiful output.

Flux Pro/Kontext — 8 Credits

Alternative option via fal.ai. Good quality with slightly different aesthetic characteristics.

Prompting for App Icons

Structure Your Prompt

"App icon for a [type] app: [description of symbol/image], [style], [color palette], [background]"

Examples

Fitness App: "App icon for a fitness tracking app: a stylized flame symbol, flat modern design, gradient from orange to red, dark background, rounded corners, clean minimal"

Note-Taking App: "App icon for a note-taking app: a simple pencil on a notepad, flat design, blue and white color scheme, soft gradient background"

Music App: "App icon for a music streaming app: abstract sound waves, gradient purple to blue, dark background, modern geometric style, glossy"

Tips for Better Icons

• ●Keep it simple — Icons display at sizes as small as 29x29 pixels. Complex designs become unrecognizable.
• ●Use bold shapes — A single recognizable symbol works better than a detailed illustration.
• ●Specify rounded corners — iOS uses rounded rectangle masks. Including this in your prompt helps.
• ●Mention color gradients — Gradient backgrounds are common in modern app icons and AI handles them well.
• ●Avoid text — Text in app icons is generally too small to read. Use symbols instead.

After Generation

Resize for All Platforms

Once you have your icon, resize it for every required size:

iOS: 1024x1024 (App Store), 180x180 (iPhone), 167x167 (iPad Pro), 152x152 (iPad) Android: 512x512 (Play Store), 192x192 (xxxhdpi), 144x144 (xxhdpi), 96x96 (xhdpi)

Test at Small Sizes

Before committing, resize your icon to 32x32 and check if it is still recognizable. If it is not, simplify the design and regenerate.

Create Round Version

Use the Round Image tool to preview how your icon looks in Android's circular mask format.

Generate Favicon

If your app has a web version, use the Favicon Generator to create all favicon sizes from your app icon.

AI-generated app icons will not win design awards, but they are more than good enough for MVPs, side projects, and concept validation.
