# AI Icon Generator

> An AI icon generator draws icons from a text description: an app icon, a set of UI icons, a favicon or a 3D game item. On Kenerate AI you describe the symbol, the style (flat, line, glossy 3D, pixel) and the colours in Image Studio, and models such as GPT Image 2.5 Sunburst, Recraft V4.1 and GPT Image 1.5 draw it — GPT Image 1.5 can return a transparent PNG directly. The files are PNG or JPG, not SVG: for a vector icon, trace the PNG in a vector app.

## Steps
1. Open Image Studio — Press “Make an icon”. Image Studio opens on GPT Image 2.5 Sunburst. Pick Square 1:1. Sign in free for starter credits.
2. Describe one icon — Write the symbol, a style from the table (flat, outline, glossy 3D, pixel), one to three colours and “centred, plain white background, no text”.
3. Build the set — Upload your favourite icon as a reference and ask for the next symbol “in exactly the same style”, or ask for a 3x3 grid of icons in one image and crop them.
4. Clean up and download — Make the background transparent, upscale if you need a large app store icon, check it at 32 and 16 px, then download without a watermark.

## In depth

### Which icon style fits your app, and what do you type?
Add the prompt words to your symbol. End every icon prompt with “centred, plain white background, no text” unless the icon needs a letter.
- Flat: Solid shapes, two or three colours, no shading. Use it for: App icons, web UI, onboarding screens. Prompt words: "flat vector-style icon, two colours, no gradients, no shadow".
- Line / outline: Even strokes with rounded ends, no fill. Use it for: Toolbars, menus, settings screens. Prompt words: "outline icon, even 2 px-style stroke, rounded caps, single colour, no fill".
- Glyph / solid: One filled silhouette in a single colour. Use it for: Tab bars, buttons, small sizes. Prompt words: "solid glyph icon, single colour silhouette, bold simple shape".
- Glossy 3D: Soft lighting, rounded forms, a gentle shadow. Use it for: App store icons, landing pages. Prompt words: "glossy 3D icon, soft studio lighting, rounded shapes, subtle shadow".
- Isometric: A small 3D object at a 30° angle. Use it for: Feature grids, SaaS pages, dashboards. Prompt words: "isometric 3D icon, 30 degree angle, clean edges, pastel colours".
- Pixel art: A sprite on a visible pixel grid. Use it for: Game items, retro apps, favicons. Prompt words: "pixel art icon, 32x32 sprite look, limited palette, crisp pixels".
- Clay / kawaii: Soft, rounded, toy-like shapes. Use it for: Kids' apps, stickers, friendly brands. Prompt words: "cute clay 3D icon, soft rounded shapes, matte pastel colours".
- App icon tile: A symbol on a full-bleed colour background. Use it for: iOS and Android launcher icons. Prompt words: "app icon, symbol centred on a full-bleed colour background, square, no rounded corners, no text".

### Icon prompts to copy
The last prompt needs your first icon uploaded as a reference in Image Studio; the rest work from text alone.
- App icon: App icon for a budgeting app: a simple white piggy bank with a small coin, centred on a full-bleed teal-to-blue gradient background, flat vector style, square canvas, no rounded corners, no text.
- UI icon set: A set of 9 outline UI icons in a 3x3 grid on white: home, search, bell, user, settings gear, heart, shopping cart, chat bubble, calendar. Identical even stroke weight, rounded caps, one colour #2563EB, equal spacing, no text.
- Glossy 3D icon: Glossy 3D icon of a paper rocket taking off, soft studio lighting, rounded shapes, orange and cream colours, subtle shadow, centred on a plain white background, no text.
- Isometric icon: Isometric 3D icon of a small cloud server with a lock, 30 degree angle, clean edges, pastel blue and lilac, centred on a plain white background, no text.
- Pixel game item: Pixel art icon of a red health potion in a round glass bottle, 32x32 sprite look, limited 8-colour palette, crisp pixels, centred on a plain white background, no text.
- Favicon: Favicon for a coffee blog: a bold solid coffee cup glyph in dark brown on a cream square, very simple shape that stays readable at 16 pixels, no text, no fine detail.
- Same style, next icon: Using the attached icon as the style reference, draw a new icon of a camera in exactly the same style: same stroke weight, colours, corner radius, lighting and padding. Centred on a plain white background, no text.

### App icon, UI icon or favicon — what's the difference?
They look alike but have different jobs, and the prompt should change with the job:
- App icon: one symbol on a full-bleed colour square, shown large on a home screen. Glossy 3D and flat both work.
- UI icon: a small, single-colour glyph or outline used dozens of times in an interface. Consistency matters more than detail.
- Favicon: the tiniest of all, often 16 px in a browser tab. One bold shape, no text, high contrast.

### What do Apple and Android expect from an app icon?
Apple's Human Interface Guidelines work from a 1024 × 1024 px square, and iOS applies the rounded-corner mask itself — drawing your own corners leaves a visible double edge. Android's adaptive icons use two layers, a foreground and a background, each 108 × 108 dp; only the inner 66 × 66 dp is guaranteed to stay visible after the launcher's mask, and the outer 18 dp on each side is kept for masking and motion effects.
In practice: generate the symbol and the background colour as separate images (or cut the symbol out with the background remover), keep the symbol well inside the centre, and let the platform round the corners.

### How do you turn an AI icon into a vector?
AI image models draw pixels. To get an SVG for a design system or an icon font:
- Generate in a flat, outline or glyph style — gradients and 3D lighting don't trace well.
- Ask for one colour on pure white, with bold, closed shapes.
- Upscale first, so the edges are smooth before tracing.
- Auto-trace the PNG in a vector app, then tidy the nodes and set the stroke widths by hand.

## FAQ
Q: Can AI make icons?
A: Yes. Describe one symbol, a style and one to three colours — “outline icon of a bell, even stroke, one colour #2563EB, centred on white, no text” — and an image model draws it. GPT Image 2.5 Sunburst, the default here, handles clean shapes and small details well; Recraft V4.1 suits flat, design-led icons.

Q: Can I get SVG or vector icons?
A: Not directly. Every image model on Kenerate returns a PNG or JPG, not SVG paths. Recraft sells vector output on its own site, but on Kenerate Recraft models return raster images too. For a vector, generate a flat or outline icon with bold, simple shapes, then auto-trace the PNG in a vector app — the simpler the icon, the cleaner the trace.

Q: How do I make a set of icons in the same style?
A: Two ways. Ask for several icons in one image (“a set of 9 outline icons in a 3x3 grid, identical stroke weight, one colour”) and crop them. Or make one icon you like, upload it as a reference and ask for the next symbol “in exactly the same style: same stroke, colours, corner radius and padding”. GPT Image 2.5 Sunburst takes up to 16 references, Nano Banana 2.1 up to 14.

Q: How do I get an icon with a transparent background?
A: Pick GPT Image 1.5 and switch on Transparent background in the settings; it returns a PNG with alpha. With any other model, ask for a plain white background and run the result through the background remover. Asking for “transparent” in the prompt alone doesn't make the file transparent — the model may simply paint a grey checkerboard.

Q: What size should an app icon be?
A: Start from a square master. Apple's guidelines use a 1024 × 1024 px app icon and the system adds the rounded corners, so don't draw them yourself. Android adaptive icons use a 108 × 108 dp canvas where only the inner 66 × 66 dp is never clipped, so keep the symbol in the middle. Generate at 1K square or larger, then upscale if you need more pixels.

Q: Is the AI icon generator free?
A: Free to start. A new Kenerate account gets starter credits, and Qwen Image 3.0 and Flux 2 Dev are free-plan models that handle simple flat icons. GPT Image 2.5 Sunburst, GPT Image 1.5, Recraft and Nano Banana 2.1 use credits from one-time packs with no subscription. Downloads have no watermark.

Q: Can I make a favicon with AI?
A: Yes — keep it brutally simple. Ask for one bold glyph on a solid square, “no text, no fine detail, readable at 16 pixels”, then shrink the PNG to 16, 32 and 48 px and look at it at that size. A favicon tool or your site builder turns the PNG into the .ico or icon files your site needs.

Q: Can I use AI icons in my app?
A: You can download and use what you make; Kenerate adds no watermark. Keep the icons original: don't ask the model to copy another app's icon or a brand's logo, and check your app store's rules before you submit. For a brand mark you plan to trademark, see the AI logo generator and have a designer refine the final file.
