Worlds: upload, switch and keep safe

Create, switch and copy worlds

Open Worlds to create a named world with an optional seed, upload a .mcworld, or switch between existing worlds. A new world generates when the server starts. The seed only affects a world that hasn't generated yet.

World changes need your server stopped. Stop it from the panel, make the change, then start it again. Only a delete runs as a protected operation: the panel takes a backup, stops the server, deletes the world, and starts the server again if it was running. If the backup fails, nothing is deleted.

Copy world makes an independent copy with a new name. It keeps the original world and its player progress. Shared add-ons remain shared, so check the add-on list before changing them.

Take a world back to Bedrock

Choose Export to Files. After the operation completes, download the .mcworld from the exports folder in Files and open it in Minecraft Bedrock. Exporting again replaces that world's previous export. Delete old exports when you no longer need them.

The export includes the world's files, embedded packs and the exact shared pack versions its activation files reference. A missing pack stops export so you don't receive a world with broken add-on references.

Upload a world

1. Export your world from Minecraft Bedrock as a .mcworld file.
2. Upload it from Worlds.
3. Activate it to play on it. An existing world with the same folder name is kept; rename the upload if you need to.

Serverk doesn't convert Java worlds into Bedrock worlds. Upload a Bedrock export. Archives with unsafe paths, unsupported links or excessive expanded size are rejected before installation.

Turn on hardcore for a world

In hardcore, each player has one life, and a player who dies can't respawn. On Bedrock, hardcore belongs to the world itself, not to the server settings, so you set it for each world.

Hardcore doesn't change the difficulty on a Bedrock server. The server takes it from the Difficulty field in Settings every time it starts, so pick Hard there for the full hardcore experience.

1. Stop your server.
2. Open Worlds, choose Set hardcore on the world, then turn the switch on or off.
3. Start your server.

A ✓ in the Hardcore column marks each world that has it on. You can turn it off again from the same place at any time.

Protect your progress

The Overworld, Nether and End share one LevelDB database. The panel doesn't reset individual Bedrock dimensions. Never edit the db directory by hand.

A recovery backup covers a delete only, so take one yourself before any large change to your world. Live backups use Bedrock's fresh save report and copy the reported file boundaries before resuming saving. If the server can't provide a consistent copy, the backup fails instead of pretending an unsafe copy succeeded.
