자주 묻는 질문

›Which UUID version is generated?

Version 4 (random) by default, generated with crypto.getRandomValues for true randomness.

›Can I generate many at once?

Yes — pick any count up to 1,000 and copy them all with a single click.

›Are UUIDs really unique?

Practically, yes. The chance of v4 UUID collision is negligible — you'd need to generate billions per second for centuries.

›Is GUID the same as UUID?

Yes. GUID is Microsoft's name for the same RFC 4122 UUID format. They're interchangeable.

›Are the UUIDs sent anywhere?

No — generation happens locally in your browser. Nothing is logged.

›Is the generator free?

Yes — fully free, no signup.
