About UUID / GUID Generator
UUIDs (Universally Unique Identifiers) are essential for generating unique keys in distributed systems, databases, and APIs. Our generator creates RFC4122-compliant version 4 UUIDs with cryptographic randomness. Generate single or bulk UUIDs with one click, copy to clipboard instantly, and use them in your applications with confidence. Perfect for database primary keys, API request IDs, file naming, and testing. All generation happens client-side using the Web Crypto API for maximum security.
