How to Transfer a Minecraft World (PC, Mobile, Between Editions)

Guide Java Bedrock

Quick answer: Java: copy the world folder out of .minecraft/saves onto a USB drive or cloud, then drop it into the saves folder on the new PC. Bedrock: use the Export World button to create a .mcworld file and open it on the new device. Java to Bedrock (or back) needs the free Chunker converter.

What you need

Java: file access to .minecraft/saves
Bedrock: the Export World button in world settings
Cross-edition: Chunker (free web converter)

Step by step

Java to Java: quit the world, open .minecraft/saves, copy the world folder to a USB stick or cloud drive.
On the new PC, paste the folder into .minecraft/saves - it appears in the Singleplayer list.
Bedrock (Windows/mobile): world list > pencil icon > scroll down > Export World. It saves a .mcworld file you can share.
On the new device, open the .mcworld file - Minecraft imports it automatically.
Java to Bedrock or Bedrock to Java: use Chunker, the free official-partner web converter - upload the world, choose the target edition and download the converted file.
Consoles: no direct file access - use Realms as a bridge (upload the world to a Realm, download it on the other console) or transfer via the same-account cloud.
Always keep a backup of the original world before converting.

Java vs Bedrock

Java uses plain folders; Bedrock uses .mcworld packages. Converting between editions changes some blocks and behaviors - Chunker reports what did not carry over.

Versions: Converted or copied worlds keep their version. Opening a world in a newer version upgrades it permanently - it will not open in older versions after that.

Frequently asked questions

Is Chunker free?

Yes - Chunker is a free web tool by Hive, partnered with Mojang, no account needed. Do not pay for world converters.

Will my builds survive a conversion?

Buildings and terrain carry over well; redstone contraptions, entities and some items can behave differently or be lost. Keep the original as backup.
