Minecraft’s fragmentation between Java Edition and Bedrock Edition has long been a headache for creators. Java boasts a vast library of .jar mods, while Bedrock uses the .mcaddon format (a renamed .zip file containing behavior packs and resource packs).
Once you have built your behavior pack (folder containing manifest.json, pack_icon.png, etc.) and resource pack:
: There is no one-click "verified" converter for logic/code. Current tools only handle specific assets like worlds (e.g., ) or textures. 2. The Porting Process (Manual Conversion) To "convert" a mod, you must break the down and rebuild it for Bedrock:
]Beware of online "JAR to MCADDON converters". They almost never work for real mods. What they actually do:
"format_version": 2,
"header":
"name": "Your Mod Name (Resources)",
"description": "Converted from Java pain",
"uuid": "GENERATE-A-RANDOM-UUID-HERE-1",
"version": [1, 0, 0],
"min_engine_version": [1, 20, 0]
,
"modules": [
Pro Tip: Bedrock uses Molang (a weird math language) instead of Java’s Math.random(). You will cry here. That’s normal.
1) Confirm what the jar contains
- Open the .jar (it's a ZIP) and inspect files: assets, classes (.class), config, resource files.
- Determine if it’s a data/resource-only pack (textures, models, sounds) or a mod with compiled Java code (most are).
