Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across space and time. UUID v4 uses random numbers, making collisions extremely unlikely (1 in 2^122).
What is UUID v4?
UUID v4 is generated using random or pseudo-random numbers. The version digit is always 4. This tool uses crypto.randomUUID() which provides cryptographically secure randomness.
Can I generate multiple UUIDs at once?
Yes. Use the quantity buttons (1, 5, 10, 25) to bulk generate UUIDs. You can copy all of them at once or individually.
Is the UUID truly random?
Yes. This tool uses the Web Crypto API (crypto.randomUUID()) which provides cryptographically secure random values, the same quality used for encryption.
