Image to Sprite Generator

Describe one game asset or upload a reference image to guide the subject. The browser downsizes the generated source, attempts to remove its plain background, and exports a PNG at your selected target size.

0/500

Downloads as a transparent PNG at your selected target size. The AI generates a clean source image first, then exports it with crisp nearest-neighbor scaling.

What happens after you click Generate

1. Your description becomes a sprite prompt

The service adds the selected style and size intent plus instructions for one centered subject on a plain background. It does not replace your requested camera angle with a fixed view.

2. An upload guides the subject

A reference image is sent as a character reference to the generation model. This is guided generation, not a deterministic pixel-by-pixel conversion, so pose, clothing, colors, and small details can change.

3. The source is resized locally

The model returns a large square source. Browser code downsizes it to the selected 32, 64, 128, or 256px frame with image smoothing disabled.

4. The background is processed locally

A flood fill starts at the image edges and clears similar, connected pixels. The result is exported as PNG. Glow, soft shadows, detailed scenery, and subjects touching an edge can leave artifacts.

A prompt recipe you can evaluate

Use a prompt with five visible decisions: subject, role, view, silhouette, and palette. For example:

Green slime enemy for a top-down dungeon, front three-quarter view, round silhouette with two short arms, three-color lime palette, no scenery, no text, readable at 64 pixels.

After generation, compare the output against those five decisions. If the silhouette is wrong, change the silhouette phrase instead of adding more style adjectives. If the result becomes painterly, simplify the material and lighting language. Generate a new variation rather than assuming the first result is representative.

Inspect the downloaded file

Open the PNG in the free Sprite QA Lab to confirm its real dimensions and alpha channel. View it on the checkerboard, then export a frame if you are checking a larger sheet. No file is uploaded.
