What is UUID Generator?
A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information without needing a central authority to issue it. Version 4 UUIDs are generated using random numbers, making collisions practically impossible even across billions of IDs.
FAQ
Are these UUIDs guaranteed to be unique?
Practically, yes. Version 4 UUIDs have so many possible combinations that the chance of a collision is negligible, even generating billions of them.
Is this data sent anywhere?
No. UUIDs are generated locally using your browser's built-in crypto API — nothing is sent to a server.
