Add Custom Worlds to your Minecraft Server

This guide will show you how to add custom worlds to your Minecraft server. This means adding worlds you can download online or even uploading a world from your single-player worlds. This guide will teach you the basics of replacing existing worlds with new ones.

To successfully download an custom world, and then upload it to your server. You will need an external archive extraction tool such as 7-Zip.

Select a World

  • You can go to any Minecraft world site and download a world you want to play.
  • Ensure this is a zip file.
  • The zip file may either contain a folder with the world files or just the contents of a world file, which changes how extraction works. For the latter, you need to create a folder, put the zip in it, and then extract.

Stop the Server

  • Login to the panel. See Access the Panel for instructions.
  • Go to the server that you wish to upload your custom world to.
  • Stop the server.
