FAQ
What is a UUID?
UUID (Universally Unique Identifier) is a 128-bit unique identifier. It is widely used for database primary keys, distributed system IDs, API tokens, and other scenarios requiring non-colliding identifiers.
Can UUID v4 collide?
UUID v4 has 122 bits of randomness, making collision extremely unlikely. Even generating 1 billion UUIDs per second, it would take about 85 years to reach a 50% collision probability.
Is my data sent to a server?
No. UUID generation uses the browser's crypto.randomUUID() API. No data is ever transmitted externally.
