About This Tool
UUIDs (Universally Unique Identifiers) are 128-bit identifiers that are practically guaranteed to be unique across all systems. They are commonly used as database primary keys, session tokens, and file names.
UUID v4 is the most common type, using random or pseudo-random numbers. It provides extremely low collision probability - you could generate a billion UUIDs per second for 100 years and have only a 50% chance of a single collision.
UUID v1 incorporates the timestamp and MAC address, making it traceable but also more sequential. This can be useful for database indexing but reveals some information about when and where it was generated.
Our generator creates cryptographically secure random UUIDs using your browser's secure random number generator.
