Before diving into the process, it is important to manage expectations. There is no universal "Convert" button that instantly turns a complex Java mod into a Bedrock add-on.
The reason lies in the architecture. A JAR file often contains deep modifications to the game's engine. The Bedrock engine is locked down tighter; .mcaddon files are essentially compressed folders containing JSON behavior packs and resource packs.
Therefore, conversion isn't just a file format change—it is often a porting process.
By following these steps, you can convert a .jar file to a .mcaddon file for use in Minecraft: Bedrock Edition. This allows you to distribute and install mods more easily on platforms that support add-ons.
Java models are blockbench-style JSON (but not directly compatible). Use the Blockbench software:
Once you have manually rebuilt the assets and logic:
.mcaddon file. Minecraft Bedrock will launch and import it.If manual conversion is too complex, consider these options: Convert Jar To Mcaddon
This is the closest you will get to a "conversion." Instead of changing the file, you change the server.
While converting JAR to MCADDON is currently a technical hurdle, the gap is closing. The creators of Minecraft, Mojang Studios, are slowly unifying the codebases. Furthermore, the community tool "Bridge." is developing smarter ways to interpret Java code for Bedrock usage.
Until then, remember the golden rule: Textures convert easily, code converts poorly. If you are trying to bring a massive Java tech mod to your phone, be prepared to wait for a dedicated developer to port it manually. But for skins, blocks, and items? You now have the power to bridge the divide yourself.
While there is no automated "one-click" tool to convert a .jar (Java Edition mod) into a .mcaddon (Bedrock Edition mod), the process involves manually porting the assets and logic because the two versions of Minecraft use entirely different coding languages—Java and C++. Understanding the Difference
Java Mods (.jar): Written in Java, these typically require loaders like Forge or Fabric. They modify the game's internal code directly.
Bedrock Add-ons (.mcaddon): Use JSON for data and JavaScript for scripting. They are composed of a Resource Pack (visuals/sounds) and a Behavior Pack (logic/mechanics). Step 1: Extract the Java Mod Before diving into the process, it is important
Since .jar files are essentially compressed archives, you need to access the source files first. Right-click your .jar file. Select Extract All or use a tool like 7-Zip or WinRAR.
Inside, look for the assets folder. This contains the textures and models you will need for your Bedrock version. Step 2: Porting Textures and Models
You can reuse the visual assets from the Java mod, but they must be reformatted.
Textures: Most .png files can be moved directly into a Bedrock Resource Pack.
Models: Java mods use .json or Java classes for models. You will likely need to recreate or import these into Blockbench, which can export models specifically in the Bedrock Geometry format. Step 3: Rewriting the Logic (Behavior Pack)
This is the most difficult part. You cannot "convert" Java code to Bedrock JSON/JS automatically. By following these steps, you can convert a
Analyze the Java Code: Identify what the mod does (e.g., adds a new mob, changes ore generation).
Create JSON Components: Use the Minecraft Bedrock Wiki to learn how to write behavior files that mimic the Java mod’s functions.
Scripts: For complex logic that JSON can't handle, you will need to write Minecraft Scripting API code in JavaScript. Step 4: Packaging the .mcaddon
Once you have your Resource Pack and Behavior Pack folders ready: Select both folders.
Right-click and select Send to > Compressed (zipped) folder. Rename the resulting .zip file extension to .mcaddon.
Double-clicking this file will now automatically import it into Minecraft Bedrock Edition. Tools to Help
