Frequently asked questions
What kind of UUIDs does this generate?
Version-4 UUIDs, which are randomly generated. They use your browser's cryptographically secure randomness for uniqueness.
Can I generate many at once?
Yes. Use the slider to generate up to 50 UUIDs at a time, then copy them individually or all together.
Are these UUIDs unique?
Version-4 UUIDs have 122 random bits, so the chance of a collision is astronomically small — safe for keys and IDs.
Is anything sent to a server?
No. UUIDs are generated entirely in your browser.
