There are online tools and software claiming to convert JAR to MCADDON automatically. Be cautious with these tools, as they may bundle additional software or malware. Always verify the source and do a virus scan on any downloaded tool.
Conclusion
Converting JAR to MCADDON can enhance your Minecraft experience by allowing you to use mods across different editions. While the process can be straightforward, compatibility is key. Not all mods will work when converted, especially if they rely on Java code. Always ensure that your Minecraft version supports the mod and that you download mods from reputable sources.
Final Tips
By following these steps and tips, you'll be well on your way to enjoying a customized Minecraft experience with your favorite mods, whether they're in JAR or MCADDON format.
Converting a Minecraft Java Edition mod (.jar) into a Bedrock Edition addon (.mcaddon) is a popular request, but because these two versions of Minecraft run on entirely different programming languages—Java for Java Edition and C++ for Bedrock—there is no single "magic button" that automatically converts them with 100% verification.
However, you can achieve this through a mix of resource porting and manual rebuilding. The Core Reality: Code vs. Assets
The Code: You cannot directly convert the logic within a .jar file to Bedrock. The Java code must be manually rewritten as JavaScript or JSON-based behavior files to work in Bedrock.
The Assets: Textures, models, and sounds can be converted relatively easily. Many tools can take the assets folder from a .jar and repackage them into a .mcpack or .mcaddon. Step-by-Step Porting Process 1. Extract the Assets A .jar file is essentially a renamed ZIP archive.
Converting a Minecraft .jar file (typically a Java Edition mod) into a .mcaddon file (the format for Bedrock Edition) isn't a simple rename or a one-click "verified" process. Because Java and Bedrock are written in different coding languages—Java and C++, respectively—they handle data, physics, and rendering differently. 1. The Fundamental Difference
A .jar file contains compiled Java code and assets designed for the PC-only Java Edition. A .mcaddon is essentially a zipped folder containing JSON files and image assets (PNGs/TGA) specifically structured for Bedrock’s "Add-on" system. You cannot simply "convert" the code; you have to translate it. 2. The Conversion Process
To successfully move a mod from Java to Bedrock, you generally follow these steps:
Extraction: You must first unpack the .jar file using a tool like WinRAR or 7-Zip to access the textures, models, and code logic.
Asset Porting: You can often reuse the textures (PNGs). However, Java's .json models are often formatted differently than Bedrock’s .geo.json models. You’ll likely need a tool like Blockbench to import the Java model and export it specifically for Bedrock.
Logic Rewriting: This is the hardest part. The Java code that defines how a mob moves or a machine works must be manually rewritten into Bedrock’s behavior packs using JSON components or Minecraft's Javascript API (GameTest). 3. Using Conversion Tools
While there is no "official" verified converter that works 100% of the time, the community uses specific bridge tools:
Bridge.: A powerful IDE for Bedrock Add-ons that helps you structure your files correctly. how+to+convert+jar+to+mcaddon+verified
Chonky (by Aruzie): An online tool specifically designed to help convert Java resource packs to Bedrock, though it focuses more on visuals than complex gameplay mechanics.
Blockbench: The industry standard for converting 3D models between the two versions. 4. Packaging the .mcaddon
Once the assets are translated, you must organize them into two specific folders:
Resource Pack: Handles how things look (textures, models, sounds).
Behavior Pack: Handles how things act (entity health, loot tables, animations).
Each needs a manifest.json file with a unique UUID (a long string of identification numbers). You then highlight both folders, zip them, and change the file extension from .zip to .mcaddon.
The term "verified" in this context usually refers to ensuring the Add-on passes Minecraft’s internal validation so it doesn't crash the game. There is no magic software that does this perfectly; it requires testing your ported assets in-game to ensure the Bedrock engine recognizes your code.
The process of converting a .jar file to a .mcaddon file is essentially the act of porting a Java Edition mod to Bedrock Edition. Because these two versions of Minecraft run on entirely different engines (Java vs. C++), there is no "one-click" verified converter that perfectly translates code. However, you can successfully convert the assets and logic by following this structured workflow. Understanding the Difference
.jar files: Contain Java code and assets for Minecraft Java Edition.
.mcaddon files: Contain "Add-ons" (Resource and Behavior packs) for Bedrock Edition.
The Challenge: Bedrock uses JSON for logic, while Java uses compiled Java classes. Step 1: Extract the Java Mod
Before you can convert anything, you need to see what’s inside the source file. Right-click your .jar file.
Select "Open with" and choose a zip utility (WinRAR, 7-Zip, or Archive Utility). Extract the contents to a new folder.
Locate the assets folder; this contains the textures and models you will need. Step 2: Convert Textures and Models
Bedrock Edition has specific requirements for image dimensions and model formats.
Textures: Most .png files can be moved directly, but Bedrock often requires power-of-two dimensions (e.g., 16x16, 64x64). There are online tools and software claiming to
Models: Java mods often use .json or .java models. Use a tool like Blockbench to import the Java model and export it as a Bedrock Geometry file.
Mapping: Ensure your folder structure matches Bedrock’s textures/items or textures/blocks format. Step 3: Create the Behavior Pack (The Logic)
This is the most complex part of a "verified" conversion. You must manually recreate the mod's functionality using Bedrock's JSON components.
Manifest File: Create a manifest.json for both your Resource and Behavior packs. Use a UUID generator to give each pack a unique ID.
Entities and Items: Create new JSON files in the entities or items folders.
Bridge the Gap: Refer to the original Java code (if available) to see variables like health, movement speed, or crafting recipes, and input them into the Bedrock component tags. Step 4: Packaging as .mcaddon
Once your Resource Pack (textures/models) and Behavior Pack (logic/scripts) are ready, you need to bundle them. Select both the Resource Pack and Behavior Pack folders. Right-click and "Compress to ZIP file." Rename the extension from .zip to .mcaddon.
Double-click the file; Minecraft Bedrock will automatically import it. 🛠️ Verified Tools for Conversion
While a full "auto-converter" doesn't exist for code, these tools are the industry standard for asset porting:
Blockbench: The best tool for converting Java models to Bedrock geometry.
Bridge.: A dedicated IDE for Bedrock Add-ons that helps automate JSON creation.
Snowstorm: Useful for converting Java particle effects to Bedrock's Molang format. Troubleshooting Common Issues
Invisible Textures: Check that your texture__list.json is updated and pointing to the right path.
Crashes on Load: Usually caused by a syntax error in the manifest.json. Use a JSON validator to check for missing commas or brackets.
Models Not Showing: Ensure the "geometry name" in your model file matches the identifier in your entity JSON.
By manually porting assets and rewriting the logic into Bedrock's component system, you ensure a stable, verified Add-on that won't break with future game updates. By following these steps and tips, you'll be
Converting a .jar (Minecraft Java mod) directly into a .mcaddon (Minecraft Bedrock add-on) is not possible through a simple file rename because they use entirely different programming languages and engines. However, you can convert certain components like textures and models using verified tools, or use specialized automation software like JavaBE to bridge the gap. 🛠️ Verified Tools for Conversion
For a "verified" workflow, you must separate the assets (textures/models) from the code (logic).
JavaBE by Stonebyte: An automation tool specifically designed to bridge Java and Bedrock by converting .jar files into Bedrock-ready .mcaddon structures with automatic pack generation.
Blockbench: The industry-standard tool for porting Java models to Bedrock. You can import a Java block/item model and export it as Bedrock geometry.
MConverter: A safe online utility for batch-converting compressed files into the .mcaddon format once you have manually organized your behavior and resource packs. 📖 Step-by-Step Porting Process
Since logic cannot be automatically converted, follow this verified manual method:
Before touching any tools, understand this: You cannot "directly" convert a JAR to an MCADDON. They are fundamentally different:
| Feature | Java (JAR) | Bedrock (MCADDON) | |---------|------------|-------------------| | Language | Java | C++ / JSON | | Render Engine | Lightweight / OpenGL | RenderDragon (custom) | | Entity System | NBT + Classes | Component-based JSON | | Scripting | JavaScript (via Rhino) / Java | JavaScript (via GoDot) / TypeScript |
A .jar mod adds new classes (code). An .mcaddon is a data pack that redefines behaviors using JSON—it cannot run raw Java code.
So what does "convert" actually mean?
It means manually recreating the features of the Java mod using Bedrock's JSON component system, then packaging the result as an .mcaddon. There is no magic one-click converter for complex mods—only workflows for simpler content like blocks, items, entities, and basic scripts.
If the JAR mod contains custom animated entities, you can use Geckolib tools to assist the conversion.
Java recipe (JSON):
"type": "crafting_shaped",
"pattern": ["###", "###", "###"],
"key": "#": "item": "minecraft:ruby" ,
"result": "item": "mod:ruby_block"
Bedrock recipe (recipes/ruby_block.json):
"format_version": "1.20",
"minecraft:recipe_shaped":
"description": "identifier": "converted:ruby_block_recipe" ,
"tags": ["crafting_table"],
"pattern": ["###", "###", "###"],
"key": "#": "converted:ruby" ,
"result": "item": "converted:ruby_block", "count": 1
This is where most tutorials lie to you. You cannot convert Java .class files to Bedrock behavior files.
You must analyze the original .jar's source code (using a decompiler like JD-GUI) and manually write JSON behavior components that mimic the logic.
Example: If the Java mod makes a diamond sword set enemies on fire, you edit the sword.json in your behavior pack and add:
"minecraft:on_hurt":
"on_hurt":
"event": "set_on_fire"
Before we begin, you must understand the technical limitations to avoid wasting your time.
