A generated image is not automatically ready for a game. Use this lab to verify the actual file: dimensions, transparent pixels, grid math, frame order, animation speed, and engine import settings. Processing happens entirely in your browser.
Inspect dimensions, alpha, slicing, and animation before import.
Local-only: your image stays in this browser and is never uploaded.
This section documents the production path used by the tools on this site. It is here so you can judge the outputs using the right expectations instead of relying on vague “game-ready” claims.
At the time of this update, requests use MiniMax image-01-live. The selected style and target size are added as prompt guidance. The model creates a square source image; the size selector is not a promise that the model drew on an exact 32 × 32 or 64 × 64 grid.
The browser downsizes the source to your selected 32, 64, 128, or 256px target with smoothing disabled. A border-connected flood fill then attempts to turn a plain background into alpha before exporting PNG.
The first frame becomes a character reference for three additional generations. The browser processes each frame, then stitches them into either a 2 × 2 sheet or a 4 × 1 strip. These are four separate generations, not one image merely labeled “sprite sheet.”
Poses, proportions, colors, and contact points can drift between frames. Background removal works best when the subject does not touch the edge and the background is flat. Always inspect a sheet at its final pixel size before shipping it.
These are selected raw JPG outputs from this site's gallery, not a random or statistically representative sample. The exact prompt is shown for each file, along with a concrete limitation we found. You can download the originals and run them through the lab above.
“Brave knight in shining silver armor with sword and red cape, side view”
The silhouette is readable, but the result is painterly rather than strict low-resolution pixel art. It works better as a concept draft than a final 32px character.
Regenerate with a simpler silhouette and fewer materials, then inspect at the final export size before using it in a game.
“Cute green slime monster with big eyes, front view”
The large outline and limited shapes survive downscaling better. This is the strongest of these three samples for a small enemy sprite.
Export at 64px, check the eye and mouth pixels, and remove any halo left by the automatic background pass.
“Magic sword with glowing blue blade and golden hilt, weapon icon”
The item remains recognizable, but the glow touches many background-colored pixels. Automatic transparency needs a manual edge check here.
Preview against both light and dark checkerboards before adding the icon to an inventory UI.
