How to put your single-player world on a server
Your survival world doesn't have to stay on one computer. Here's how to move it onto a server so friends can play in it too.
Find and zip the world
- In Minecraft, click Singleplayer, select the world, then Edit → Open World Folder.
- Go up one folder so you can see the world's folder itself, and zip it (right-click → Compress / Send to → Compressed folder).
Upload it to Jump
- In the panel, stop the server.
- In Files, delete or rename the current
worldfolder, then use Upload world and pick the zip. It's unpacked as the server's world. - Start the server and join.
Worlds bigger than a few hundred megabytes upload faster over SFTP with FileZilla or WinSCP; the address and username are on the Files page.
Things to check
- Same or newer version: set the server to the version the world was last played on, or newer. Opening a world in an older version can corrupt it.
- Nether and End: single-player keeps them inside the world folder; Paper keeps them in
world_netherandworld_the_end. Paper converts this automatically on first start. - Modded worlds need the same mods on the server, or modded blocks disappear.
- Your inventory: player data is per account, so it comes across once you join with the same account.
Questions
Can I upload a Bedrock world?
Bedrock worlds (.mcworld) use a different format. Convert them with a tool such as Chunker first, then upload the Java world.
Will I lose my old server world?
Not if you rename the old world folder instead of deleting it, or download it from Files first. Paid plans also have backups to restore from.
