UUID Generator

Generates UUID v4 (random, cryptographically secure) or v7 (timestamp-based, chronologically sortable) identifiers, in a configurable quantity, with or without hyphens, in uppercase or lowercase, and lets you validate a pasted UUID by identifying its version and variant. Version and variant bits are set exactly per the current standard.

Absolute uniqueness isn't guaranteed: a UUID v4's collision probability is extremely low, but not mathematically zero.

The data is processed on your device and is never sent to the server.

Frequently asked questions

Is a UUID generated here guaranteed to be unique worldwide?
Absolute uniqueness can't be guaranteed — a UUID v4 has an astronomically low collision probability, but not a mathematically zero one.
What's the difference between v4 and v7?
v4 is fully random. v7 embeds a millisecond Unix timestamp at the start, so UUIDs generated in chronological order also sort correctly as text.
