Trademarks
"Minecraft" is a trademark of Mojang Synergies AB. "Microsoft" is a trademark of the Microsoft group of companies. NBTBox is not one of Mojang's or Microsoft's products and is not endorsed by them. Where this site uses the word "Minecraft" (for example, "NBT editor for Minecraft saves"), it is solely a descriptive reference indicating which files the tool opens — the term is not used as a brand, logo, or trade name of this site. No game art, game assets, screenshots, logos or official fonts are used on this site.
No game content
NBTBox works with NBT (Named Binary Tag), a publicly documented binary data format. This site does not contain, distribute or link to game software, game code or copyrighted game assets. It only manipulates data files that users open from their own computers.
User responsibility
Save files are important data. While the editor is built and tested to round-trip files without loss, you use it at your own risk: always back up your world before replacing an edited file. See the Terms of Service for the full limitation of liability.
Accuracy of content
The format guide and other content on this site are provided for informational purposes. The NBT format as used by the game may change in game updates; we aim to keep the documentation current but make no guarantee that every detail reflects the latest game version.
