Summary

Chunker converts Minecraft worlds between Java Edition and Bedrock Edition, processing the worlds locally on the user's machine. It can carry over level settings and world data such as blocks, biomes, and tile entities, as well as multiple dimensions, containers, items, and in-game maps. It can also upgrade or downgrade worlds between supported game versions. Inputs include world folders, ZIP archives, and MCWORLD files, with drag-and-drop support. Conversion and export settings can be adjusted, and export settings can be saved for later conversions. Chunker includes a command-line interface for conversion and workflow integration; using it requires Java 17 or higher. Entities and player inventories are not converted, and structure data such as villages and strongholds is listed as unsupported or limited. Chunker is free and open source under the MIT license. It is available on Windows, macOS, Linux, and through a web interface. Supported version ranges vary by edition, so check that a world falls within them before converting.

Who it is for

Chunker suits Minecraft players who need to move worlds between Java and Bedrock editions or change a world’s game version. Its CLI and reusable export settings may also suit users integrating conversion into a workflow.
