Frequently Asked Questions
- What is a UUID?
- A UUID (Universally Unique Identifier) is a 128-bit ID that's practically unique. This generator creates UUID v4 (random) values using the Web Crypto API. Free, no signup.
- Are these UUIDs cryptographically random?
- Yes. The generator uses the browser's Web Crypto API (crypto.getRandomValues) so each UUID v4 is cryptographically random and suitable for IDs and tokens.
- Can I generate multiple UUIDs at once?
- Yes. Choose how many to generate (e.g. 1, 5, 10) and copy all with one click. No data is sent to any server.
