Dungeon Map Maker for DnD Rooms, Corridors, and Encounters
Design a dungeon encounter map for your next tabletop session. Build rooms and corridors, add terrain and props, align the grid, and export a PNG battle map for VTTs or print.
Quick answer: A dungeon map maker helps Dungeon Masters create rooms, corridors, caves, ruins, and other encounter-scale layouts for tabletop play. RPG Map Editor focuses on browser-based dungeon prep with terrain painting, props, tactical grids, saves, and PNG export.
Build a playable dungeon room
Open the browser editor, block the room and corridors, add tactical props, and export a PNG before game night.
Quick answer
What is a dungeon map maker?
It is software for building explorable interior or underground spaces where movement, doors, cover, hazards, and the grid need to stay readable. RPG Map Editor exports visual PNG maps; VTT walls, doors, and lights are configured inside Roll20 or Foundry after import.
Free Dungeon Map Maker for D&D remains the core use case: Make a dungeon map for one real session, then save or export it when the layout is playable.
Not best for
Full campaign world maps, automated dungeon generation claims, native Foundry scene export, Roll20 dynamic lighting export, walls, doors, or token automation.
Fast prep
Build dungeon encounters faster
Start with the playable footprint first: room entrances, corridor width, cover, hazards, and grid alignment. Add props after the tactical layout works so the map helps the encounter instead of hiding it.
What you can create
Rooms, corridors, ruins, caves, and grid layouts
Rooms
Build readable encounter rooms with entrances, cover, and token space.
Corridors
Connect rooms with halls that support reveal pacing and movement.
Ruins
Use broken walls and terrain to create partial cover and sight lines.
Caves
Paint organic edges, chokepoints, and rough terrain for underground fights.
Traps, objects, and props
Use supported props and stamps for doors, cover, hazards, furniture, and dressing.
Tactical grid layouts
Keep square count and grid alignment clear before export.
Export for play
PNG maps for Roll20, Foundry VTT, or print
Export the dungeon as a PNG, upload it as a Roll20 map image or Foundry scene background, and align the platform grid. For print, proof the scale before session day.
