Bedrock to Java Converter

About This Tool

The Bedrock to Java Converter enables cross-edition migration of Minecraft worlds and assets. It ingests Bedrock world data, including terrain blocks, biomes, structures, and entity definitions, and outputs a Java Edition compatible world and asset set. The process preserves as much data as possible while adapting block IDs, data formats, and behavior to Java semantics.
The tool applies domain rules for block and entity mappings, chunk translation, biome alignment, and data pack compatibility. It performs input validation, version checks, and generates a detailed migration report that highlights any unsupported features or skipped items.
Audience includes players ports for single-player worlds, server operators porting maps to Java servers, and map designers delivering cross-edition experiences. Its automated workflow reduces manual rework, improves reproducibility, and provides exportable Java world artifacts suitable for deployment.
Core capabilities include block remapping, entity compatibility checks, biome translation, and data pack alignment, with optional partial migrations and delta updates for iterative workflows. Examples include porting a Bedrock world to Java 1.20 with a corresponding asset pack, or exporting both the world and resource data for server use.
