Offline UUID
For servers with online-mode=false. Computed in your browser.
A server without account verification derives the UUID from the nick, letter case included.
How to find a Minecraft UUID and create a whitelist.json
In the “Player” card, enter the nick or UUID of a Java Edition account and click “Search”. You get the UUID dashed, plain and for NBT.
View the skin from the front and back, and save it as a PNG with “Download skin”.
For a server with online-mode=false, type the nick into the “Offline UUID” card. The value is calculated right in your browser.
In the “whitelist.json and ops.json” card, paste up to 50 nicks, choose the file and server mode, then click “Create file”.
Download the file and upload it to the server's main folder. Load the whitelist with /whitelist reload; ops.json needs a server restart.
About this tool
This Minecraft UUID lookup finds a player's unique UUID by username, in every format: dashed, plain and as an NBT int array. It works the other way too, turning a UUID into the current name.
You see the player's skin from the front and back and can download it as a PNG. For servers without account verification (online-mode=false) it calculates the offline UUID the server assigns to that player.
Enter up to 50 names at once and get a ready whitelist.json or ops.json for your server. We don't store anything.

Frequently asked questions
Answers to the questions people ask most about this tool.
How do I find a Minecraft player's UUID?
Enter the username in the field above. The tool finds the Java Edition account's UUID and shows it with and without dashes. It works the other way too: get the current name from a UUID.
What is an offline UUID?
The UUID a server with online-mode=false derives from the username alone. It differs from the account UUID, which is why players lose inventories and data after online-mode is switched. The tool shows both values.
How do I create a whitelist.json?
Enter the players' names (up to 50), choose whitelist.json and the server mode, then download the file. Upload it to the server folder and load it with /whitelist reload. The whitelist must be on (white-list=true).
