How to Use the Level.dat Editor

Upload and edit your Minecraft level.dat file directly in the browser. Modify game rules, difficulty, time of day, weather, spawn point, world border, and view active mods. Works with both vanilla and modded worlds.

Accepts level.dat files — the world settings file found in every Minecraft save folder (e.g., .minecraft/saves/MyWorld/level.dat).

Quick Steps

1Drag and drop your level.dat file onto the upload area, or click to browse
2Edit settings using the visual form — game rules, difficulty, time, weather, and more
3Review your changes in the changes panel
4Click Download to save the modified file
5Replace the original level.dat in your world folder with Minecraft fully closed

Example Use Cases

Enable keepInventory or disable mobGriefing without opening the game
Change the world spawn point to a new location
Adjust the world border size and center for a server event

Tips

Always close Minecraft completely before replacing the file, or the game will overwrite your edits on save

Your file is processed entirely in the browser — nothing is uploaded to any server
