About UUID
UUID (Universally Unique Identifier) is a 128-bit identifier, typically rendered as 32 hexadecimal digits in 5 groups. This tool uses the browser's built-in cryptographically secure random generator (crypto.getRandomValues) to produce UUID v4, ensuring extremely high uniqueness — suitable for database primary keys, session IDs, API keys, and more.
