Game engines: Unity, Godot, Tiled

PNG for any engine#

A plain PNG export is already engine-ready: transparent, straight alpha, at native pixel size. In your engine set the texture to Point (no filter) filtering and turn compression off for crisp pixels.

Sprite sheets + JSON#

File ▸ Export ▸ Sprite sheet (PNG) and Sprite sheet JSON together give you a packed image plus:

{
  "frames": { "sprite 0.aseprite": { "frame": {"x":0,"y":0,"w":32,"h":32}, "duration": 100 }, ... },
  "meta": { "image": "sprite-sheet.png", "size": {"w":256,"h":32}, "frameTags": [ {"name":"walk","from":0,"to":3,"direction":"forward"} ] }
}

This is the common TexturePacker / Aseprite JSON shape — most importers and community scripts read it directly.

Tiled maps#

For a tilemap project, File ▸ Export ▸ Tiled (TMX / TSX) writes a .tmx map and .tsx tileset that open in Tiled. Per-tile collision, role, name, tags and custom properties you set in the Tileset editor are carried through.

Texture atlas#

File ▸ Export ▸ Texture atlas packs the current frame's layers (or slices) into one image plus a JSON of named rectangles — a generic format any custom pipeline can parse.
