16/32 Bit Heightmap Generator

A free tool that turns real-world elevation data into 16-bit PNG and 16/32-bit EXR heightmaps, texture maps, 3D models (STL, OBJ, GLB, 3MF), contours and posters for Unreal Engine 5, Godot, Blender, Unity and 3D printing. It runs entirely in your browser: nothing is uploaded, and there are no accounts or paid plans. It needs JavaScript, which is turned off here.

Settings are stored in the link itself, for example the Grand Canyon at 64 km.
