Introducing the Tilemap Editor: Paint Game Levels in Your Browser

We built the Tilemap Editor because laying out a game level should be something you can just do — open a page, drop in a tileset, and start painting — without installing a desktop tool or wrestling with a project file. It's live now in our Tools section, and everything happens in your browser: nothing you load or make is ever uploaded.

Slice a tileset, paint a level

Drop in a tileset PNG and the editor slices it into a tile strip for you — set the tile size, margin and spacing and it adjusts instantly. From there you paint straight onto the grid with the tool that fits the moment: Stamp for single tiles, Rect for blocks, Fill for whole regions, plus an eyedropper to grab a tile you've already placed and an eraser to take it back. Grab several tiles at once to stamp a chunk of scenery in one stroke, flip tiles on the X or Y axis, and lean on unlimited undo/redo while you experiment.

Real maps are built in layers, so the editor is too. Stack as many as you need — ground, details, collision, overlays — and toggle each one's visibility and opacity as you work, so you can paint a rooftop without disturbing the street beneath it.

Auto-tiling that connects for you

Hand-placing every corner and edge of a path is the tedious part of tilemapping, so we added an Auto tool. Give it a terrain set and it picks the right tile for each cell based on its neighbours — draw a rough line and it lays down clean, connected roads, walls or rivers with the corners and junctions worked out automatically. There's a built-in auto-tile demo you can load and paint on immediately to see it in action.

Export to Tiled — or straight into the Game Maker

When your map is ready, export it as a Tiled-compatible JSON file or a flattened PNG. The JSON drops into engines and pipelines that already speak the Tiled format, and you can import a map back into the editor at any time to keep working on it — nothing is one-way.

Best of all, it plugs straight into the rest of our gamedev suite: a map you paint here imports directly into the Game Maker, so you can go from a blank grid to a playable level without leaving the browser.

Try it now

The Tilemap Editor is free and runs entirely on your machine — no account, no uploads, no install. The fastest way to get a feel for it is to load the sample tileset and paint a few tiles.

Open the Tilemap Editor and build your first level — we'd love to see what you make with it.
