What does UUID Generator actually do?

The UUID generator draws new identifiers with the browser’s crypto API. Version 4 is random. Version 7 includes a timestamp component and is still not a secret. Nil is all zeros. Generating a UUID does not register it in a database.

What UUID versions are supported?

Common options include v4, v7, and nil — check the tool UI for the exact set available.

Are generated UUIDs sent to a server?

No. IDs are created with browser crypto APIs on your device.

Is this UUID generator free?

Yes — free online GUID/UUID generation with no account.
