Minecraft Bedrock Pack files. These are essentially renamed ZIP archives containing JSON metadata, textures, sounds, or JavaScript/TypeScript behaviors designed specifically for the Bedrock engine. Can You Convert Java Mods to Bedrock Add-ons?
While manual conversion is best for custom content, some community tools can help map textures:
: Right-click the .jar file and select Rename . Change the .jar extension to .zip .
A compressed ZIP archive renamed to allow the Bedrock engine to automatically import resource packs, behavior packs, or skin packs. It relies heavily on structured JSON files and optional JavaScript scripting to modify game behavior safely. Phase 1: Re-creating Textures and Models convert jar to mcpack
Useful for converting Java .nbt structures to Bedrock structures. Summary Table: Converting JAR to MCPACK Java (.jar) Method Bedrock (.mcpack) Method Conversion Difficulty Recipes JSON files JSON files Easy (Rename/Re-path) Loot Tables JSON files JSON files Textures Moderate (Re-map) Models .java / .obj .geo.json Hard (Blockbench) Logic/Code Compiled .class JavaScript / JSON Very Hard (Rewrite)
It must include two unique (Universal Unique Identifiers).
"format_version": 2, "header": "description": "Ported functionality from Java Edition", "name": "Ported Mod Resource Pack", "uuid": "INSERT_FIRST_UUID_HERE", "version": [1, 0, 0], "min_engine_version": [1, 20, 0] , "modules": [ "description": "Resources", "type": "resources", "uuid": "INSERT_SECOND_UUID_HERE", "version": [1, 0, 0] ] Use code with caution. 2. Zipping and Renaming Minecraft Bedrock Pack files
Because you cannot execute Java bytecode inside Bedrock’s C++ engine, "converting" a .jar means manually translating its assets and behavior logic into Bedrock's JSON and JavaScript structures. Phase 1: Deconstructing the Java JAR File
Go to and select Bedrock Geometry ( .geo.json ). Phase 3: Building the Bedrock Behavior Logic
Summary
GUIs (menus, inventory screens) are coded differently and require manual reconstruction.
Used by Minecraft Java Edition. It contains compiled Java bytecode, textures, and assets designed for the Java Virtual Machine (JVM).
