Export part of a Minecraft Java world as .schem

Turn a build from a Java world save into a single .schem without opening the game: zip the world (or pick one .mca region), select the area and export.

What to do

  1. Zip the world folder that contains the region folder, or use one r.x.z.mca file.
  2. Use Suggest main build or type exact X, Y and Z bounds for the area.
  3. Exports are limited to 200 million positions and 32,767 blocks on each axis.
  4. Load the .schem in a compatible WorldEdit installation or inspect it in Schematic Studio. Check the destination Minecraft version and preservation limits before pasting.

Privacy and reliability

Files are parsed on your device. In the viewer, the original is also kept in your private library after the storage notice and stays private until you publish it; the standalone converter never uploads anything.

TipKeep a backup of the original. Browser conversion is convenient, but it does not replace world backups or source control.
