LevelSmith Pro

2D level editor for game developers that exports Tiled-compatible TMJ files — running 100% offline in a single HTML file.

LevelSmith Pro is the full version of the tile-based 2D level editor built for game developers. Paint unlimited tile layers with a fast tile picker, use brush, rectangle, fill, and erase tools, place entities and objects with typed properties, preview parallax backgrounds, and playtest your maps in walk mode with basic collision.

Everything is unlocked: unlimited maps, unlimited layers, unlimited tilesets, and all exporters — including full TMJ export (Tiled-compatible JSON/TMJ with correct firstgid, GID flips, and parallax defaults) plus LDtk conventions.

One-time $9.99 purchase — yours forever. 100% offline, single-file HTML.
