Frequently asked questions
What is a UUID v4?
A UUID v4 is a 128-bit random identifier, typically shown as 36 characters with hyphens. It does not encode a MAC address or timestamp.
How many UUIDs can I generate at once?
Between 1 and 100 per click. Increase the count, generate again, then copy or download whatever you need.
Are these UUIDs random and unique?
Yes for practical purposes. The browser’s crypto.randomUUID API supplies cryptographically strong randomness for version 4 UUIDs.
Does this generator send data to a server?
No. IDs are created on your device. Deskutil never receives the generated values.
