Tilemap Editor
Paint a bounded color tilemap with undo, then export a PNG or JSON snapshot locally.
4–32 tiles per side; 4–64 px per exported tile; 50 undo strokes. Applying dimensions starts a blank map. No import, layers, autosave, or recovery.
A QUICK WALKTHROUGH
How to use this tool

- Choose a color or eraser, then paint by pointer or keyboard.
- Set the PNG tile size and export PNG or JSON before leaving the page.
Tilemap Editor
The grid is 4–32 tiles per side and PNG tiles are 4–64 pixels, so output is at most 2048 × 2048. Undo keeps at most 50 strokes in this page. Applying new dimensions or clearing replaces the current in-memory drawing. There is no tileset/image import, layers, animation, collision data, autosave, or project recovery.
