The simplest approach: export a .mcworld, then send it over

Moving a Minecraft world to a new phone is essentially treating that world save as a file and relocating it:

  1. Export on the old phone. In Bedrock, export the target world as a single .mcworld file (it’s really a ZIP with a renamed extension that contains the complete world save).
  2. Send it to the new phone. Use AirDrop, the Files app, or any cloud storage to send the .mcworld across. Between two iPhones, AirDrop is usually the least hassle.
  3. Open it to import on the new phone. On the new phone with Bedrock installed, open the .mcworld and the system imports the world into your world list.

This step doesn’t strictly require a tool. What TopoBlocks adds is one-tap export/sharing, plus help figuring out the cause if the next step’s import gets stuck — it does not replace the game’s built-in export, and it never overwrites your source file, keeping the original version traceable every time. For import details on different devices, see How to import a .mcworld on iPad.

Import failed on the new phone? Usually it’s a structure problem

If opening the .mcworld on the new phone shows an “import failed” message, in the vast majority of cases the file isn’t broken — the archive’s folder structure is wrong: level.dat isn’t at the root, or an extra folder wraps the world, so the game can’t find it.

In this case you can use TopoBlocks’s free on-device diagnosis: it points out the file type, version, and structure issues. A simple structure repair is also free and produces a new .mcworld that imports correctly, while the original file stays untouched. Only genuinely complex corruption goes to advanced repair, and before any payment it shows the problem, the success probability, the risks, and the refund policy. Prices are shown in-app.

Want a smoother switch: restore directly from a cloud backup

If you’d rather not manually export and transfer every time, keep a backup on hand and restore directly on the new device when you switch:

  • On-device snapshots — free, keeping versions of your world locally that you can roll back to anytime.
  • World Pro cloud backup (¥22/month, 20GB) — back up to the cloud and keep version history; both upload and restore require your explicit authorization. Prices are shown in-app.

Either way, restore creates a new copy by default and never overwrites any existing world — your current world and the original file, along with their hashes, are preserved and traceable. This is a product red line. Data that was never backed up and is now fully deleted from the device cannot be recovered out of thin air, so the earlier you keep a copy, the safer you are. To learn more about how cloud backup works, see How to back up a Minecraft world to the cloud.

One more note: importing the same world onto two phones just gives you two separate copies, each played on its own — they don’t sync in real time. To play the same world together on two devices at once, you need to deploy it to a server — see Can two devices play the same world together.
