In this post, we'll explore how to convert a JAR file to an MCAddon portable file, making it easy to use your mods on any computer.

Minecraft Java Edition mods (distributed as .jar files) are built on Java and use the Java Edition modding APIs (Forge, Fabric). Bedrock Edition uses a completely different architecture: add‑ons (behavior packs and resource packs) using JSON, scripting (in some versions), and platform-specific constraints. Direct binary conversion from a Java .jar to a Bedrock .mcaddon is not possible. This paper presents a migration strategy: analyze the Java mod’s features, map them to Bedrock capabilities, reimplement logic using Bedrock add‑on formats and available scripting, then package as .mcaddon.

There is one tool that attempts this: PojavLauncher (or similar launchers). But that doesn't convert the mod—it runs the entire Java Edition on your Android/iOS device. Minecraft Java Edition mods (distributed as
That is not a .mcaddon file. That’s an emulator. And it runs at 5 FPS on most phones.
