Minecraft Username to UUID Converter

A UUID (Universally Unique Identifier) is a permanent ID assigned to every Minecraft account. Unlike usernames which can change, UUIDs always stay the same.

Server admins use UUIDs for whitelists, bans, and permission plugins. UUIDs are more reliable than usernames since players can change their names.

Full UUID has dashes (e.g., 069a79f4-44e9-4726-a5be-fca90e38aaf5). Trimmed UUID removes the dashes. Some plugins require one format or the other.
