Frequently asked questions
Is this UUID Generator free to use?
Yes, it is completely free with no sign-up or usage limits.
Are these UUIDs sent to a server?
No. Every UUID is generated locally in your browser using the Web Crypto API — nothing is sent anywhere, and each one is independent and unpredictable.
What version of UUID does this generate?
Version 4 (random), the most commonly used type — 122 bits of randomness with the version and variant bits set per RFC 4122, so collisions are astronomically unlikely.
How many can I generate at once?
Up to 100 at a time. Set the quantity and click Generate, then use Copy or Download to grab the full list.
Can I generate UUIDs without hyphens or in uppercase?
Yes, both options are available and apply immediately to the current list.
