How to Upload Your Own World

To use your own world, zip the world folder, upload it, then tell the server which folder to load. Most failed uploads come down to zipping the wrong thing or hitting the size limit, both easy to avoid.

How to upload it

1. On your PC, find your world folder. For singleplayer: press Win+R, type %appdata%\.minecraft, then open saves and find your world.
2. Right-click the entire world folder (not just the region subfolder inside it) and compress it to a .zip.
3. Open Files and upload the zip.
4. If it's over roughly 1 GB, the web upload will fail or hang. Set an SFTP password in Account and upload with a tool like WinSCP instead, no size limit there.
5. Once uploaded, use the panel's unarchive option to extract it into its own folder.
6. Open Server Properties and set the world name to exactly match your uploaded folder's name.
7. Restart the server and confirm the right world loads.

Zip the whole world folder, top to bottom. A zip with only region or level.dat inside will upload fine but won't actually load as a world.

Still stuck?

World uploads but chunks are missing: the transfer likely got corrupted partway. Re-zip and try SFTP, in smaller pieces if the world is very large.

Bringing a world over from a modpack: make sure your server runs the matching pack and loader version first, see How to Install a Modpack.

Server won't start after uploading: see How to Read the Crash Log.

Nothing here matches what you're seeing: open a support ticket, a screen-share is often the fastest way to sort out a stuck large-world upload.
