UUID Generator

A UUID (Universally Unique Identifier) is a 128-bit identifier that is guaranteed to be unique across space and time. Version 4 UUIDs are randomly generated using a cryptographically secure random number generator, making them ideal for database primary keys, session tokens, and distributed systems where coordination between ID generators is impractical. This tool uses the browser's native crypto.randomUUID() API for maximum security.
