Converting a file is a common goal for players looking to port Minecraft Java Edition mods or resource packs over to Minecraft Bedrock Edition (PE, Xbox, Windows, iOS, and Android). Because Java and Bedrock use fundamentally different coding architectures (Java vs. C++), you cannot simply change the file extension and expect a code-heavy Java mod to work. However, for asset-based mods, textures, and cross-platform framework porting, a systematic manual or tool-assisted conversion is highly effective.
Create a file named manifest.json inside your resource pack root folder and paste the following structure:

You can use any portable text editor (like ) to create these files. Resource Pack Manifest
However, you can successfully recreate and convert the logic, assets, and behaviors of a .jar mod into a portable .mcaddon format by breaking the mod down and rebuild it using Bedrock's native scripting and JSON architecture. Here is the complete, step-by-step guide to doing it manually. Understanding the Architecture Difference
