Open the .jar file using an archive utility like 7-Zip or WinRAR. Navigate to assets/[mod_id]/models/item/ or /block/ .
I can provide tailored JSON templates or specific step-by-step scripting guides based on your needs. Share public link
While there isn't a simple "one-click" converter for every mod, you can use specialized tools and manual steps to bridge the gap. Below is a guide for a post on this topic.
. Because Java Edition is built on Java and Bedrock Edition is built on C++, the code inside a file cannot be "translated" automatically.
Go to and save the .geo.json file. Step 4: Build the Bedrock File Structure Convert Jar To Mcaddon
Success Rate: Moderate
This step requires strong programming knowledge and is not automatic.
The conversion process involves several steps:
Converting a (Java Edition) mod into an .mcaddon (Bedrock Edition) file is a highly sought-after but complex task because the two versions of Minecraft use entirely different coding languages— Java vs. C++ . Open the
Test iteratively
Choose or Bedrock Block/Item as your target format.
Most conversions fail because Bedrock lacks certain Java features (e.g., custom render layers, complex NBT data). Be prepared to simplify.
Ensure block and item textures match Bedrock's naming conventions and dimensions. Share public link While there isn't a simple
By breaking down the Java .jar archive, translating the textures and models via Blockbench, and utilizing Bedrock's modern JSON components and JavaScript engine, you can successfully bring legacy Java experiences to millions of Bedrock players across the world. To help tailor this guide further, let me know: What are you trying to convert?
Paste these into your respective manifest.json files to ensure Minecraft registers them as unique content. Step 3: Recreating Mod Logic (Java to JSON/Scripting)
Because the two editions are built on completely different codebases (Java vs. C++), simply renaming a .jar to .mcaddon will not work; the internal structures are entirely incompatible. A proper conversion must translate the Java‑side content into Bedrock’s JSON‑based add‑on system.

Open the folder to locate the assets directory. This contains the textures and models you will need. Step 2: Convert Java Textures to Bedrock
