2D Tiler
What it is
2D Tiler is a browser-based editor for making 2D game levels, tilesets, pixel assets, palettes, and exports. Its layered map tools include painting, erasing, filling, selecting, autotiling, and object placement. Terrain options cover standard, diagonal, sparse, and 16-slot Wang autotile workflows, plus weighted terrain fill. A built-in image editor includes drawing, shape, selection, crop, move, and blur tools. Palette imports support GIMP GPL, Adobe ASE, Aseprite, JASC PAL, Paint.NET TXT, and HEX lists. An AI asset workspace supports OpenAI, Google Gemini, xAI, and Together AI provider families for creating tilesets, sprites, backgrounds, icons, interface elements, and visual effects. The app runs locally in a browser and uses browser-based project storage. Its native formats are .2dp projects, .2dm maps, and .2dt tilesets. Map workflows support exports for Tiled, Godot 4, Unity, GameMaker, Defold, Phaser, tIDE, and Mappy. The editor is open source under the MIT License and is free forever, with no recurring subscriptions or arbitrary limits. Tiled map and tileset files are supported, while Tiled project container import and export is planned.
