Frequently asked questions
Which UUID version is generated?
Version 4 (fully random), following RFC 4122, produced by your browser's cryptographically secure random source via crypto.randomUUID().
Can I generate UUIDs in bulk?
Yes — up to 100 at once. You can also switch to uppercase or remove the dashes, then copy the whole batch with one click.
Are the UUIDs logged anywhere?
No. They are created locally in your browser and never transmitted — once you close the tab they are gone.
