How to Change the World Seed

A world seed determines how your world is generated. Changing it will apply to the next time a new world is created.

⚠️ Note: Changing the seed alone will not change your current world. You need to reset your world first for the new seed to take effect. Check How to Reset your world article.

Steps

1. Stop your server.
2. Go to the Files tab in your panel.
3. Open server.properties.
4. Find the line that starts with level-seed=.
5. Enter your desired seed. For example:

level-seed=12345

6. Save the file.
7. Delete your current world folder(s) (world, world_nether, world_the_end).
8. Restart your server. A new world will be generated using the seed you set.

📝 Note: Leaving level-seed= blank will generate a random seed each time a new world is created.
