Generation happens entirely in your browser using the Web Crypto API, so no identifiers or requests ever touch a server.
Frequently Asked Questions
- What version of UUID does this generate?
- It generates UUID v4 — randomly generated identifiers, the most common type used in modern apps, databases, and APIs.
- Can I generate more than one UUID at once?
- Yes, set the count to generate as many UUIDs as you need at once, then copy them all together.
- Are the generated UUIDs sent to a server?
- No — UUIDs are generated locally in your browser using the Web Crypto API, so nothing is transmitted or logged.
