UUID stands for Universally Unique Identifier – a 128‑bit label used for unique identification.

Version 4 (random) UUIDs are generated from random numbers, ensuring near‑zero chance of collision.

Perfect for database keys, session tokens, API identifiers, and distributed systems.

Standard format: 8-4-4-4-12 hexadecimal digits (e.g., 123e4567-e89b-12d3-a456-426614174000).

Our generator uses crypto.randomUUID() (secure, RFC‑compliant) – no server, no tracking.

UUIDs are generated locally using your browser's secure crypto API. No data sent anywhere.

Generate up to 100 UUIDs at once. Copy all or download as a text file – one per line.

Fully responsive, touch‑friendly. Generate UUIDs on your phone, copy with one tap.
