Background
2D game background generator
Block in the horizon line, the big shapes and the colours on a grid. The model paints a background with that composition: wide (3:2), tall (2:3) or square.

Every picture on this page was made for it: a starter template's sketch, one line of description and an art style, then the same finishing steps as your own results. Nothing was retouched.
After you generate
A built-in image editor
Open any result under “Edit assets”: layers with blend modes; rectangle, ellipse, lasso and magic-wand selections; levels, hue and temperature; filters, clone, text and a history panel. Saving adds a new version and the original stays. Layers, selections, clone, text and history are in the pro mode, which is free.
One-click style unification
Put the assets in one project and give it an art style. One click then repaints every 2D result in the project in that style, and runs the project's 3D models through the de-AI pass with it. The AI mode costs 5 credits or more per image, with the total shown before anything runs; the free offline mode evens out palette and outlines only.
How to make one
- 1Create a “Scene background” and pick the frame: 3:2 for side-scrollers, 2:3 for phones held upright, 1:1 for anything else.
- 2Paint the layout in flat colours: sky, far mountains, the tree line, the ground. The model keeps where things sit and how much of the frame they take.
- 3Describe the mood and the time of day, pick a style and generate.

Good to know
- It is one flat image. The layers of a parallax background (sky, far hills, near trees) don't come as separate files.
- No characters are painted in: the prompt asks for an empty scene, so your own sprites can go on top.
- Wide backgrounds come out at 1536×1024. Upscale before using one full screen at 1080p or above.
Questions
Can a background loop sideways?
Not yet: the left and right edges of a background are not made to meet. Skyboxes and seamless textures are, because they have to wrap.
Can I use the results in a commercial game?
Yes. Our terms hand over whatever rights we hold in what you generate. Each image model also has terms of its own, so look at the one you picked, and a result that looks like an existing character or logo is still that character or logo.
Does the file say it was made with AI?
Yes, in a machine-readable tag in the file's metadata. The picture itself isn't touched.
