Here’s a concise review of the process to convert a .jar (Java Edition mod/plugin) to a .mcpack (Bedrock Edition add-on):
This is how most Java mods end up on Bedrock. A developer must:
.jar file to retrieve textures (assets/textures) and models (assets/models).behavior_pack/entities and resource_pack) to define how the item behaves in Bedrock..zip and rename the extension to .mcpack.my_mod.mcpack/
mods/
my_mod.jar
assets/
my_mod/
textures/
block.png
models/
block.obj
manifest.json
Luckily, textures are universal.
textures/items/ folder from the JAR files into your new resource_pack/textures/items/..class files (bytecode) and assets.There is no software that reads Java bytecode and spits out a Bedrock JSON behavior pack. The logic is too different. If you see a website claiming "JAR to MCPACK Online Converter," it is a scam or a virus.
Why? Java mods rely on reflection and coremods (changing the game's base code). Bedrock does not allow this. Bedrock uses an event-driven JSON system.
If you want Bedrock add-ons, learn the Bedrock Add-on documentation (JSON + JavaScript). If you need Java mods, stick to Java Edition.
Converting a Minecraft Java file directly to a Bedrock is not possible for gameplay mods (like those found on Forge or Fabric), as the two versions use completely different coding languages. However, you can convert resource packs (textures/assets) found inside .jar files or use specialized server software like to bridge the gap 1. Converting Textures (Resource Packs) contains textures you want on Bedrock: Extract the Assets : Rename your and extract it. Use a Converter : Tools like the Java to Bedrock Converter PackConverter by GeyserMC can automatically restructure the files for Bedrock. Finalize the File : Once converted, compress the new folder into a and manually change the extension to 2. "Create Paper" & GeyserMC (Server Side)
If your goal is to "create" a environment where Java and Bedrock players can play together using Java mods/plugins: Setup a Paper Server
is high-performance server software for Java Edition that supports plugins. Install Geyser
plugin to your Paper server. This allows Bedrock players to join your Java server without needing to convert any files to : Pair Geyser with the convert jar to mcpack
plugin so Bedrock users don't need a Java account to log in. 3. Summary of Differences Java Edition (.jar) Bedrock Edition (.mcpack) Java code (compiled) JSON/C++ (scripting) Conversion Requires full rewriting of code Possible for textures only Note on "Create Paper": If you meant the crafting recipe for paper in-game, place 3 Sugar Canes
in a horizontal row on a crafting table to produce 3 sheets of paper. ElixirNode
Converting a Minecraft Java resource pack (stored as a .jar or .zip) to a Bedrock Edition .mcpack requires more than just renaming the file. While both versions use similar assets, Bedrock requires a specific manifest file and different file structures to function. Method 1: Automated Conversion (Recommended)
The easiest way to bridge the gap between Java and Bedrock is using specialized tools that handle the file renaming and technical mapping for you.
Itsme64’s Texture Pack Converter: An online tool that automates the process of renaming files, moving assets, and converting image formats (like PNG to TGA) to ensure compatibility. Use the Texture Pack Version Converter to upload your Java pack.
PackConverter (GitHub): A library specifically designed for converting Java Edition packs to Bedrock. It provides both a GUI and CLI version for more advanced users. Method 2: Manual Conversion
If you prefer to do it yourself, follow these steps to restructure the files manually:
Extract the JAR: Rename your .jar file to .zip and extract its contents using a tool like 7-Zip or WinRAR.
Clean the Folders: Delete everything except the assets folder. Inside assets/minecraft, keep only the textures folder and its contents. Here’s a concise review of the process to convert a
Create a manifest.json: Bedrock requires this file in the root directory to identify the pack. You must include a unique UUID (Universally Unique Identifier) which can be generated at UUIDGenerator.net.
You can copy a manifest template and fill in your pack's name and description.
Compress and Rename: Highlight the assets folder, your manifest.json, and your pack.png icon. Right-click to "Send to Compressed (zipped) folder".
Change Extension: Rename the resulting .zip file to .mcpack. When prompted about changing the file extension, select "Yes". How to Use the .mcpack
Once converted, simply double-click the .mcpack file. Minecraft Bedrock will automatically open and begin the "Import Started" process. After a successful import, you can activate the pack in Settings > Global Resources > My Packs.
Converting a file to an is a common hurdle for players trying to bring Minecraft Java Edition assets into the Bedrock Edition ecosystem. While files are typically Java mods and
files are Bedrock resource or behavior packs, the conversion process often starts with turning that Java archive into a standard compressed folder. The Fundamental Difference .jar (Java Archive):
Used for Minecraft Java Edition mods or game versions. It is essentially a specialized ZIP folder containing Java code and assets. .mcpack (Minecraft Pack):
A zipped collection of resources (textures, sounds, or behaviors) designed for Minecraft Bedrock Edition (Windows, iOS, Android, Console). Step 1: Convert .jar to .zip Extract Assets: Unzip the
The first move is to turn your Java file into a standard ZIP so you can access the files inside. Rename manually: In your file explorer, right-click the file and change the extension to If you can't see the extension, go to the tab in File Explorer and check File name extensions Use a tool: If manual renaming feels risky, you can use the Itsme64 JAR to ZIP Converter to handle the swap in seconds. Step 2: Prepare the Assets for Bedrock Crucial Note:
Simply renaming a file doesn't always make it compatible. Java textures and Bedrock textures use different folder structures and naming conventions. For Texture Packs: You may need to use a tool like Blockbench to port models or manually move files into a manifest.json structured folder. For Sound Packs: You may need to convert
files and ensure they follow the Bedrock sound directory path. Step 3: Convert .zip to .mcpack
Once your assets are correctly structured inside your ZIP folder: Rename again: Change the extension from (all lowercase). Confirm the change:
A warning will pop up asking if you're sure about changing the extension; select Import to Minecraft: Double-click the new
file. Minecraft Bedrock should automatically launch and begin the import process. Troubleshooting Common Errors "Import Failed":
This usually means your internal folder structure is wrong or the manifest.json file is missing/invalid. "Duplicate Pack":
You already have a pack with the same UUID installed. You'll need to change the UUID inside the manifest.json before converting. Mobile Users: On iOS, you can use the Documents by Readdle
app to rename and zip files properly before opening them in Minecraft. Are you converting a texture pack , and what (PC, mobile, console) are you trying to move it to?
