What is this website for?

MCUUID is a project designed to make finding, converting, and looking up Minecraft player UUIDs and usernames, simple and easy. A UUID is a unique identifier issued by Mojang to all users when they purchase the game. This tool is useful when, for example, locating player.dat files on a Minecraft server.

A big thank you to Crafatar for providing player avatars.
