What Minecraft World Converter is
Minecraft World Converter is a free, open-source Windows desktop tool for converting saved worlds between Minecraft Java Edition and Bedrock Edition. Conversion works in both directions, and the tool can also change versions within one edition, including downgrades such as Java 1.20 to Java 1.16. Users select a target game version, with the latest version set by default. Available targets depend on the Amulet library; unsupported choices may use the nearest compatible version. The graphical interface displays live logs and avoids command-line operation. Multiple saves can be imported and converted in batch to a chosen output directory. Optional forced repair resaves chunks in an attempt to repair damaged data. The project is built on Amulet Core, a Python library for reading and writing Minecraft save formats, and is packaged as the Windows executable mcconvert.exe with PyInstaller. The MIT-licensed project recommends Python 3.10 or 3.11 and Windows for development. Its README warns that conversion is high risk and advises backing up original worlds first.
