UUID Generator

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information. UUID v4 uses random generation, making collisions virtually impossible.

Choose the UUID version (v4 recommended), set how many to generate (1-100), and click Generate. Copy individual UUIDs or all at once.

UUIDs are generated using crypto.randomUUID() in your browser. Nothing is sent to any server.

UUID v1 is based on timestamp and MAC address, while v4 is fully random. v4 is more commonly used as it doesn't leak machine information.
