Minecraft Java Edition ( .jar ) and Minecraft Bedrock Edition ( .mcaddon / .mcpack ) operate on entirely different engines. Java mods often run custom code directly on the machine, while Bedrock Add-ons use a data-driven system—primarily JSON files—to define behaviors and resources [1].
Here is a general guide to using these tools.
Once your Behavior Pack (BP) and Resource Pack (RP) are functional: Select both the MyMod_BP and MyMod_RP folders. Right-click and . how to convert jar to mcaddon
Move block and item textures from the extracted Java pack into MyMod_RP/textures/blocks/ or MyMod_RP/textures/items/ .

Locate the assets and data folders. This is where all textures, models, and recipes live. Step 2: Set Up the Bedrock Add-on Structure
Most textures can be reused, but you may need to rename them to match Bedrock's directory structure. Once your Behavior Pack (BP) and Resource Pack
| Java Mod Feature | Bedrock Equivalent | |----------------|--------------------| | Custom block (e.g., furnace-like) | block.json + minecraft:custom_components | | New mob AI | Entity Behavior Tree ( .json ) | | Custom recipe | recipes/ folder with recipe JSONs | | New item | item.json + texture reference | | Event handling | Animation Controllers & Scripting (JavaScript via Script API) |
Before you start, know that a simple file extension change won't work.

Java mods use .class files to inject code directly into the game. Bedrock Add-ons use JSON for data-driven behavior and JavaScript (GameTest Framework) for complex logic.
