What it does
Dungeon Map Doodler is a free browser drawing tool for tabletop maps. It includes terrain brushes, objects, text and freeform drawing.
Use it when a map needs an irregular outline rather than only square rooms. Dynamic brushes can fill terrain while placed stairs, doors and labels communicate how the space works. Check the exported scale against the tabletop or printed grid before the session.
Set feet per box and box size along with the grid’s height and width. The export is an image for printing or another program. You can also import a dungeon generated with donjon and continue drawing around that starting layout.
