Make a Windows .ico Icon from a Text Description, Free with AI

The problem it solves

You built a script or a little app and it needs an icon. You can't draw, stock icons all look the same, and the one you did find looks great at full size and like a smudge in the system tray.

Icon Creator is the browser version of a desktop tool I built for exactly this. You describe the icon, an AI draws it, and you check it at the tiny sizes icons actually get used at before you save anything.

How it works

1. Paste your OpenRouter key. The first time you open it, it asks for one and checks that it works. That's a one-time setup.
2. Describe the icon. For example, "a blue lightning bolt inside a rounded square." Tick Transparent background if it's going on a toolbar or tray, or Use brand colors to give it up to three hex colors.
3. Click Generate and look at the preview strips. They show the icon at real tray sizes on a light and a dark background.
4. Nudge it if needed, then pick the sizes you want and click Save .ico or Save .png.

The nudge buttons

After each result you get seven buttons: Simpler, More contrast, Bolder, More iconic, Fewer colors, Fill the frame and Different style. Each one re-runs your description with that adjustment, so you can steer the result without rewriting your prompt.

Simpler and More contrast are the two that most often rescue a muddy icon.

Writing a prompt that works

Icons are small, so simple beats detailed every time. Name one clear object, say what shape it sits in, and keep it to two or three colors. Skip text inside the icon: letters turn into smudges at 16 pixels.

You need an OpenRouter key

The drawing is done by an outside image model, so you need a key of your own to reach it. Make an account at openrouter.ai, add a little credit, create a key, and paste it in. You pay OpenRouter directly for each image, usually a few cents. I add no charge of my own.

Why I ask for your email

It tells me who is actually using the tool, which helps me decide what to keep building.

Here's where everything else goes. Your key is stored only in this browser and is sent only to openrouter.ai. Your description goes to the image model you picked so it can draw. Nothing is stored on any server of mine, and the finished icons are saved straight to your device.

I might send you a note now and then about other free tools I build. I will never sell or give your email to anyone else.

Questions people ask

What does it cost?

The tool is free. The images are billed by OpenRouter to your own account, usually a few cents each.

Is my key safe?

It's kept in this browser only and never sent anywhere except OpenRouter. Clearing your browser data removes it, and Settings has a Clear button.

Why does my icon look bad at 16 pixels?

Too much detail. Try the Simpler and Bolder nudges, and cut it down to one clear shape.

What sizes go into the .ico file?

You choose from 16, 32, 48, 64, 128 and 256 pixels. One .ico holds several sizes, and Windows uses the small ones where space is tight.

Can I use the icons commercially?

That depends on the terms of the image model you chose. Check that model on OpenRouter before using an icon in something you sell.
