Open the Java mod's documentation (or decompiled code). For every custom item, you need to create:

|----------------|-------------|
| A Bedrock add-on from a Java mod | Recreate it manually – write behavior packs, resource packs, and scripts for Bedrock |
| To use a Java mod on Bedrock | Not possible – play Java Edition for Java mods |
| A .mcpack or .mcaddon file | Create a valid Bedrock behavior/resource pack, then zip and rename to .mcaddon |

Bedrock uses the same PNG format as Java. However, the file naming is different.
Action: Copy all .png files from the Java JAR into your new Bedrock resource pack's textures/ folder.
There is no direct converter, but there are bridge tools for developers:
| Tool | Purpose | | :--- | :--- | | Blockbench | Converts Java Block/Item models into Bedrock models. | | Bridge. V2 | Converts Java loot tables & recipes to Bedrock format (partial success). | | Chunker (by Hive) | Converts Java worlds to Bedrock, but not standalone mods. |
Do not use online "JAR to MCADDON" websites. They either: Open the Java mod's documentation (or decompiled code)
If you are a server owner who just wants your Java plugins to work for Bedrock friends: Stop looking for a converter and install GeyserMC. It will save you weeks of headache.
If you are a developer wanting to publish on the Bedrock Marketplace: You must learn the Bedrock addon format from scratch. Start with the official Microsoft documentation on Behavior Packs.

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. Example: Converting a "Fire Wand"
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:
Converting a .jar file to a .mcaddon file involves packaging your Minecraft mod into a format that Minecraft Add-Ons can understand. .mcaddon files are essentially .zip files with a specific structure that Minecraft: Bedrock Edition can use to install add-ons, including mods, behavior packs, and resource packs.
To create a .mcaddon file from a .jar file that contains your mod, you'll need to follow these steps. Note that this guide assumes you have a basic understanding of Minecraft modding and access to a computer with a compatible operating system.
