0 tiles

Drag a selection on the image, then confirm the capture to add it to the list below.

If the source image has a checkerboard or flat backdrop, remove it first so Tiled receives a transparent PNG.

0 / 0 captures selected

Captured areas will appear here with their tile grid preview after you confirm a selection.

Layout Board

Drag sprites into a new sprite sheet

Select one or more captures first, then drag them freely here to rebuild your layout.

Use Cases

What problems does this tool solve?

Misaligned AI-generated sprite sheets

When characters, tiles, or props do not sit neatly on a consistent grid, you can crop the usable areas and rebuild them into a cleaner tileset.

Broken slicing after importing into Tiled

If a 32x32, 64x64, or custom tileset keeps slicing incorrectly, adjust tile size, margin, and spacing here before exporting a new PNG.

Picking useful assets from a large generated image

Keep only the sprites you want, then reorganize them into a more practical sprite sheet for level design and map editing.

FAQ

Frequently asked questions

What is a sprite sheet?

A sprite sheet is a single image that contains many game assets such as characters, props, terrain tiles, or animation frames.

What is a tileset?

A tileset is a collection of assets arranged on a consistent grid so tools like Tiled Map Editor can slice and place them correctly.

Why are AI-generated sprite sheets often misaligned?

AI image generation focuses on visual composition rather than strict pixel-grid rules, so spacing, borders, and tile sizes often drift off-grid.

Does it support 32x32 and 64x64 tiles?

Yes. It also supports custom tile sizes, margin, and spacing, which is useful for different pixel-art workflows.

Can I use it for game assets generated by ChatGPT?

Yes. If the image can be loaded in the browser, this tool can help you crop, align, rebuild, and export it into a Tiled-friendly tileset.
