Frequently asked questions

What is a UUID v4?

A UUID v4 is a 128-bit identifier generated using random or pseudo-random numbers, making collisions extremely unlikely even across independent systems.

Can I generate multiple UUIDs at once?

Yes. You can generate a batch of UUIDs, copy them all, or download the full list as a text file.

Is the generation done on a server?

No. UUIDs are generated entirely in your browser. Nothing is sent to or logged by a server.
