FAQ
- Is crypto.randomUUID() used?
- Yes. This tool uses the Web Crypto API (crypto.randomUUID or crypto.getRandomValues) for cryptographically secure random generation. Math.random is never used.
- What UUID version is generated?
- UUID version 4 (random). This is the most widely used version for generating unique identifiers without coordination.
- Are the UUIDs generated on the server?
- No. All UUIDs are generated locally in your browser. Nothing is sent to any server.
- Can I validate an existing UUID?
- Yes. Use the validator section at the bottom to check if a string is a valid UUID and identify its version.
