Sprite Fusion

Sprite Fusion is a free online tile map editor for 2D games. You import any tile set, draw the map with an intuitive editor, and export the result straight into Unity Tilemap or a Godot TileMap scene. Automated tile and collision handling removes the manual work of tagging each tile, and maps can be saved, loaded, and shared. The description positions it for retro games and 2D level design in general.

- Import your own tile set and draw a map.

- Let the editor handle tiles and collisions automatically.

- Export to Unity or Godot in one click.

- Save, load, and share map files.

- Indie developers building 2D games.

- Retro and platformer creators who need fast level layout.

- Unity and Godot users who would rather not place tiles by hand.

This is a map editor, not a game engine, so gameplay, scripting, art, and audio all still belong to you and your engine. You also supply the tile art, and the quality of the result depends on it. Free web tools can change their terms or add limits, and export formats may be updated in ways that need re-importing, so keep your own copy of any project. Large maps can also get unwieldy in a browser, so work in sections. Processing speed depends on file size and network conditions, so retry later if a task stalls during peak hours. Run one full task end to end first, then expand once you are comfortable with the workflow and the result quality. Save a backup of the original file before large batch jobs, and keep an exported copy of key results in case the page or service becomes temporarily unavailable.
