Select a Java world area for .schem export

Review the imported world, keep the entire detected area, ask for the main build suggestion or enter exact X, Y and Z bounds.

01

What to do

  1. Use Suggest main build as a starting point, not as an authoritative selection.
  2. Verify all six minimum and maximum coordinates before export.
  3. Exports are limited to 200 million positions and 32,767 blocks on each axis.
02

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.
