What it is

2D Tiler is a free, open-source web editor for 2D game levels, tilesets, pixel assets, palettes, and exports. Its layered map tools include painting, erasing, filling, selection, autotiling, and object placement. Terrain options cover standard, diagonal, sparse, and 16-slot Wang workflows, plus weighted fills. A built-in image editor offers drawing, selection, cropping, moving, and blur tools, among others. Palette imports include GIMP GPL, Adobe ASE, Aseprite, JASC PAL, Paint.NET TXT, and HEX lists.

An AI workspace can create tilesets, sprites, backgrounds, icons, UI elements, and visual effects using OpenAI, Google Gemini, xAI, and Together AI provider families. Provider choice determines availability, billing, content rules, and image privacy. The editor runs locally in the browser and stores project data through a browser-based workflow. Native formats are .2dp projects, .2dm maps, and .2dt tilesets. Map workflows support Tiled, Godot 4, Unity, GameMaker, Defold, Phaser, tIDE, and Mappy formats; raster support includes PNG, JPG, WebP, BMP, and GIF where the selected path allows it. Tiled map and tileset files are supported, but Tiled project-container import and export is planned, not available.
