Converting a file to an format is more than a simple rename; it involves bridging the gap between Minecraft: Java Edition (which uses files for mods) and Minecraft: Bedrock Edition (which uses for add-ons).
is essentially a ZIP archive, the internal code and structure are incompatible between the two versions of the game. The Core Conflict Java Mods (.jar):
These contain compiled Java code and assets designed to run on PC-based servers or clients using loaders like Forge or Fabric. Bedrock Add-ons (.mcaddon): These are ZIP-based containers that hold Bedrock-specific Resource Packs Behavior Packs
). They use JSON files for logic and Bedrock-specific formats for models and textures. Conversion Process
Because the underlying engines differ, you cannot "convert" the actual logic (code) of a Java mod into a Bedrock add-on automatically. You can, however, convert the (textures and models). 1. Extract the Assets
is a ZIP archive, you can open it with any archive tool or use an online JAR-to-ZIP converter to see the folders inside. Locate the folder—this contains the textures and models. 2. Convert Textures and Models You must manually adapt these assets for Bedrock: Ensure they match Bedrock's folder structure (e.g., textures/items textures/blocks Use tools like Blockbench to export Java models into Bedrock-compatible 3. Create Manifest Files Every Bedrock pack requires a manifest.json
file. This file tells Minecraft the pack’s name, description, and unique IDs (UUIDs). You can generate these using a Manifest Generator 4. Package as .mcaddon
Once you have your folders ready (Resource and Behavior packs): Zip the folders:
Select both the Resource Pack folder and the Behavior Pack folder. Create a single file containing both. Change the file extension from
Ensure you have "File name extensions" enabled in your OS settings to see and change the extension. Automated Tools

.mcaddon File Structure.mcaddon file is a .zip file with an .mcaddon extension.If you meant converting a Java Edition resource pack (.jar containing assets) to a Bedrock resource pack (.mcpack), that's sometimes possible by extracting textures and models and converting them to Bedrock’s format.
Converting a file (Java Edition mod) directly into an file (Bedrock Edition) is not a simple file rename; it requires "porting" because the two versions of Minecraft use entirely different coding languages (Java vs. C++) and file structures. 1. Understanding the Difference : A Java Archive file used for Minecraft: Java Edition : A specialized file containing resource and behavior packs used for Minecraft: Bedrock Edition Microsoft Learn 2. How to "Convert" (Porting Process)
Because these formats aren't compatible, you must manually extract the assets and re-code the logic: Extract the .jar Assets : Change the extension from
and extract it. This gives you access to the original textures, models, and code. Convert Textures/Models : Use tools like the Texture Pack Version Converter to make Java assets compatible with Bedrock. Rewrite Behaviors : Java mods use files, while Bedrock Add-Ons use
for behaviors. You will need to manually recreate the mod's logic in Bedrock's behavior pack format. Package as .mcaddon Place your manifest.json into a folder. Compress the folder into a Rename the file extension from 3. Available Automation Tools
For those looking to simplify this complex workflow, independent developers have created specialized toolkits:

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
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 Converting a file to an format is more
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.
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

Image to Map: If the mod relies on specific UI or map elements. Step 2: Understand
Converting a JAR file to an MCADDON is a common goal for players looking to bring the depth of Java Edition modding into the more flexible Bedrock Edition environment. However, because Java Edition is built on Java and Bedrock is built on C++, a direct "one-click" conversion of complex gameplay mods is currently impossible.
Instead, the process depends on what specifically is inside that JAR file—whether it's a Resource Pack (textures/models) or a Gameplay Mod (new mechanics/entities). Understanding the Conversion Limits
Resource Packs (Easiest): JAR files containing only textures, sounds, and simple models can often be converted automatically using online tools or simple manual renaming.
Gameplay Mods (Hardest): JAR files containing Java code (e.g., Forge or Fabric mods) cannot be automatically converted. These must be manually recreated from scratch as Bedrock Addons, using the Java code only as a reference. Step-by-Step: Converting a Resource Pack JAR to MCPACK
If your JAR file is a texture pack, you can follow these steps to bring it into Bedrock:
I cannot directly convert a .jar file to a .mcpack or .mcaddon file for you because I am an AI text model and do not have access to your files or the specific tools required for decompilation and recompiling.
However, I can explain in detail (the "long paper" version) why this conversion is complex, the different types of .jar files you might have, and the step-by-step methods to attempt the conversion manually.
Before attempting a conversion, you must understand why these formats are not interchangeable.
| Feature | JAR (Java Edition) | McAddon (Bedrock Edition) |
| :--- | :--- | :--- |
| Language | Java (JVM bytecode) | C++ with JavaScript/TypeScript (Gametest Framework) + JSON |
| Archive Type | Standard ZIP (usually .jar) | ZIP (renamed to .mcaddon or .mcpack) |
| Contents | .class files, assets (JSON, PNG, OGG) | manifest.json, behavior_pack/, resource_pack/, .js scripts |
| Rendering | OpenGL (LWJGL) | RenderDragon (proprietary) |
| Entity System | NBT + DataWatcher | JSON components + Actor Properties |
Critical Reality: No automated software (not even advanced AI tools in 2026) can perfectly translate Java logic into Bedrock's component system. The "conversion" is a manual porting project.
