Instead of Chunker
Chunker alternatives
Chunker is aimed at moving Minecraft worlds between Java Edition and Bedrock Edition. It converts settings, blocks, biomes, tile entities, dimensions, containers, items, and in-game maps, and can upgrade or downgrade worlds across game versions. Inputs include world folders, ZIP archives, and MCWORLD files; conversion happens locally. It is free on Linux, macOS, Windows, and the web, with adjustable conversion and export settings and a command-line interface that requires Java 17 or higher.

A reason to look elsewhere is that Chunker does not convert entities or player inventories, and structure data such as villages and strongholds is unsupported or limited. The options below focus on other jobs, from editing individual NBT files or Bedrock player data to pruning chunks or changing biomes. When comparing them, consider whether you need whole-world conversion or a narrower edit, which Minecraft edition and file types you use, and whether a desktop, browser, local web, or command-line workflow suits you. Each alternative differs in the data it can change and the scope of its work.
