UUID Generator

We support UUID v1 (timestamp-based), v4 (random), and v5 (namespace-based). V4 is most commonly used for its randomness, v1 for time-ordered IDs, and v5 for deterministic IDs.

UUID v4 uses cryptographically strong random numbers, providing about 122 bits of randomness. The probability of a collision is extremely low (1 in 2¹²²).

Yes, you can generate multiple UUIDs in bulk and copy them all at once in your preferred format.

Yes, when using v4 (random) UUIDs, we use cryptographically secure random number generation for maximum security.
