For simple mods (new blocks, items, simple mobs), the effort is reasonable. For complex tech or magic mods, consider whether the Bedrock ecosystem has a similar existing add-on instead.
Development_Behavior_Packs (for entity behaviors, functions, recipes, and loot tables) Step 2: Create the Manifest Files
Select both the Resource Pack folder and Behavior Pack folder. Compress them together into a single file. Rename the file extension from .zip to .mcaddon .
If the .jar file you downloaded is actually a (often used for texture packs or custom UI overlays, though they are sometimes distributed as .jar files to be used with mod loaders), you can easily convert the textures to work on Bedrock. Step 1: Extract the Resource Files Download the .jar file on your computer. Convert Jar To Mcaddon
Once your resource and behavior packs are finished and fully integrated:
Essential for converting Java entity models into the .geo.json format required by Bedrock. Summary of File Extensions .jar Java Edition mod (compiled code) .zip Standard archive used to view internal mod files .mcpack A single Bedrock resource or behavior pack .mcaddon A container holding multiple .mcpack files JAR to ZIP Converter - CloudConvert
Locate the .jar mod you want to convert. Ensure you have the original file and that you are complying with its license terms. If the mod is protected by a license that prohibits redistribution or modification, you cannot legally convert it for public release. For simple mods (new blocks, items, simple mobs),
Ensure your Behavior Pack folder and Resource Pack folder are in the same directory. Select both folders and compress them into a .zip file. Rename the .zip file extension to .mcaddon .
For simple mods—specifically those that add new items, blocks, or textures without complex new mechanics—automated tools are your best bet.
Method 1: Converting Java Resource Packs to Bedrock (.mcpack) Compress them together into a single file
Tools like allow Java clients to join Bedrock servers—but they do not convert JAR mods . Only vanilla gameplay works.
Java mods can override core engine rendering and physics. Bedrock Add-ons are sandboxed; they can only alter what Mojang's official API explicitly exposes.
