Frequently asked questions
What type of UUID does this generate?
Version 4 (random) UUIDs, produced with your browser’s cryptographically-secure
crypto.randomUUID(). Each one is virtually guaranteed to be unique.Are these UUIDs truly random?
Yes. They are generated from a cryptographically-strong random number source built into your browser, not a predictable sequence.
Can I remove the hyphens or change the case?
Yes. Toggle “remove hyphens” for a 32-character string, “uppercase” for capital letters, and “wrap in quotes” to paste straight into code or a list.
Is anything generated on a server?
No. Every UUID is created privately in your browser. Nothing is requested from or sent to any server.
