Converting Java Mods to Bedrock: Is a ".jar to .mcaddon" Tool Real?
If you’ve spent any time in the Minecraft modding community, you’ve likely seen the question: "How do I convert a .jar mod to an .mcaddon for Bedrock?"
It sounds like a dream—taking those massive Java Edition mods and dropping them onto your phone, console, or Windows 10 Bedrock world. But here is the direct truth:
There is no "one-click" converter that can automatically turn a Java mod into a working Bedrock
Because Java and Bedrock are built on entirely different coding languages (Java vs. C++), "converting" a mod is actually more like rebuilding
it from scratch. However, that doesn't mean it's impossible to bring your favorite features over. Here is the breakdown of what works, what doesn't, and the tools that actually help. 1. The Language Barrier: Why "Jar" Doesn't Just "Work" Java Edition mods (the files) are written in and rely on mod loaders like . Bedrock Edition "Add-ons" ( JavaScript for their logic. Java Mods: Can change almost any part of the game's code. Bedrock Add-ons: convert jar to mcaddon work
Are officially supported but limited to what Mojang's API allows. 2. What CAN You Actually Convert?
While you can't convert the "code" of a mod, you can often port the You can port Java texture packs to Bedrock using tools like Itsme64’s Converter ModifiedCommand's Browser Tool 3D Models:
If a Java mod adds a cool new mob, you can export the model using Blockbench and re-import it as a Bedrock entity. If you want to move a whole map, tools like can convert world files between editions. 3. The "Manual" Porting Process If you are determined to make a
mod work on Bedrock, you’ll need to follow a manual workflow:
Here’s a step-by-step write-up on converting a Java Edition .jar mod to a Bedrock Edition .mcaddon (add-on). This is not a direct conversion — the two versions use completely different codebases (Java vs. C++) and APIs. Instead, you must recreate the mod’s functionality for Bedrock. Converting Java Mods to Bedrock: Is a "
Create RP/textures/terrain_texture.json:
"resource_pack_name": "convert_ores",
"texture_name": "atlas.terrain",
"texture_data":
"ruby_ore":
"textures": "textures/blocks/ruby_ore"
Create RP/blocks.json to link the block ID to the texture:
{
"format_version": "1.20.0",
"minecraft:block": {
"description":
"identifier": "moreores:ruby_ore"
,
"components": {
"minecraft:unit_cube": {},
"minecraft:material_instances":
"*":
"texture": "ruby_ore"
}
}
}
BP (behavior pack) and RP (resource pack).Short Answer: No, not with a converter tool. Long Answer: Yes, you can recreate the mod's content manually.
If you are searching for a website where you upload a .jar and download a .mcaddon—stop looking. It does not exist because the code languages are not compatible.
However, by following this guide—extracting assets, rebuilding behavior JSON, and using GameTest scripts—you can port 60-80% of content-based Java mods to Bedrock. For the remaining 20% (core engine changes), you must accept that Bedrock works differently. Step 5: Register the Texture in the Resource
Final Pro Tip: Search for "Bedrock equivalent of [Mod Name]" before attempting a manual port. The community has likely already built an MCADDON that does what your JAR does.

| Tool | Purpose | |------|---------| | Blockbench | Convert Java block/item models to Bedrock geometry | | bridge. | Visual editor for Bedrock add‑ons | | Java decompilers (Fernflower, CFR) | Read Java mod source to understand logic (but not convert) | | Convertors (JAR2BDS, MCAddon Maker) | Extremely limited – only copy assets or rename, cannot convert code |
⚠️ Be wary of online “JAR to MCADDON converters.” They either fail completely or only extract textures/sounds – not the actual mod logic.
