Frequently asked questions

What version is generated?

This tool generates RFC4122 version 4 UUIDs using cryptographically strong randomness where available.

Are UUIDs unique?

v4 UUID collisions are astronomically unlikely for practical purposes. They're suitable as identifiers in many systems.

Is anything uploaded?

No. UUIDs are generated locally in your browser and never sent to our servers.
