JavaBE - .jar Into .mcaddon

Go to files

JavaBE is a free Windows desktop tool that helps convert Java Edition mod content into Bedrock add-on format.

It is built to reduce manual setup work and automate the hardest parts of conversion, so creators can test faster and spend less time fixing pack structure issues by hand.

What JavaBE Does

JavaBE processes user-supplied mod files and automatically builds Bedrock-ready output, including:

Entity/model conversion and geometry cleanup
Animation conversion and controller generation
Texture/sound/particle/language conversion (when supported)
Behavior + resource pack structure generation
Manifest/UUID/dependency setup
Validation + auto-fixes for common Bedrock load errors
Script bridge fallback for Java logic that cannot be mapped 1:1

Important Reality (Current State)

JavaBE is actively in development, and not every Java mod can be fully ported yet.

Some mods convert very well. Others may convert partially, need manual cleanup, or fail due to engine differences between Java and Bedrock (custom rendering, deep Forge/Fabric hooks, advanced networking logic, etc.).

We are continuously improving compatibility and adding support over time.

Responsible Use / Creator Rights

JavaBE does not include or grant rights to third-party mod content.

Users are responsible for following original creator licenses and permissions.

Do not sell/paywall converted output unless original rights explicitly allow it
Do not redistribute converted content unless the original creator/license permits it
