Biome Painter is a stand-alone program for editing biome information in Minecraft save files using the Anvil file format introduced in Minecraft 1.2.


After loading a region, left click to paint your selection over the map of the region and right click to erase.

Once an area has been selected it can be filled with a particular biome or have all instances of a particular biome within the selection replaced with another biome.

In addition to arbitrary biomes, the biome generation from various versions of Minecraft can be used to populate the selected area with the biomes that would have been at those particular coordinates while playing that version.


Biome Painter requires the .NET Framework 4.0 (Client Profile) or better to run on Windows. It is possible to run it on Mac with the Mono platform.
