Minecraft Java 1.21.4+ to Bedrock Converter & Geyser Mapper
Drop Java .zip here
Max size 500MB
Auto-fix Compatibility Issues
Automatically strips invalid display nodes like ON_SHELF and converts uppercase directories to lowercase. Bedrock rejects models that contain these.
ON_SHELF
Generate Geyser Mappings
Produces a geyser_mapping.json compliant with Format V2 (1.21.4+ definition parsing alongside Legacy support).
geyser_mapping.json
Convert Custom Characters (Fonts)
Parses assets/*/font/*.json arrays into Bedrock-readable Glyph mappings and moves texture images automatically.
assets/*/font/*.json
Developer Strict Mode
Fail conversion immediately if an item condition cannot be mapped accurately instead of attempting safe fallbacks. Useful for debugging pure 1.21.4+ implementations.
