Our verdict on Chunker
Chunker is an open-source application for converting Minecraft worlds between Java Edition and Bedrock Edition. It is suited to players, creators, server administrators, and technical users who need to move worlds between editions or game versions. The tool supports upgrades and downgrades across documented Minecraft releases, with support spanning Bedrock 1.12.0–1.26.50 and Java 1.8.8–1.21.11 and 26.1–26.3. It is available free of charge under the MIT License and is maintained by Hive Games.
Its strongest fit is workflow flexibility. Chunker provides an Electron-based graphical desktop interface for Windows, macOS, and Linux, alongside a web interface and a Java command-line interface for automated conversion workflows. Users can import supported world archives, including .mctemplate and tar archives, preview worlds before conversion, and review conversion logging. Custom settings cover blocks, biomes, dimensions, pruning, and converter behavior, while exported settings support repeatable work across conversions.
Chunker is a focused world-conversion tool rather than a general Minecraft development suite. The published capabilities center on edition and version conversion, archive importing, configuration, previewing, and logging; it is not aimed at mod packaging, plugin editing, or script editing. That makes it a strong choice for cross-edition migration and repeatable conversion workflows, especially when command-line automation or reusable settings matter. Users seeking tools for modifying mods, plugins, or scripts should choose a product built around those tasks instead. Support is provided through GitHub Issues and listed project resources.
