Spec score 6.6 #16 of 18 in Minecraft World Converters

What it 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 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. Multiple saves can be imported and converted in batch to a chosen output directory. An optional forced-repair mode resaves chunks in an attempt to repair damaged data. The graphical interface provides live logs and does not require command-line operation. The project is built on the Amulet Core library and packaged as the Windows executable mcconvert.exe. Available target versions depend on Amulet updates, and unsupported choices may use the nearest compatible version. The README recommends Python 3.10 or 3.11 with Windows for development. The project uses the MIT license and advises backing up original worlds because conversion is high risk.
