Set how many you need, up to 100 at a time, and click Generate. Each one is a version 4 UUID, meaning it's built from random data rather than your device's identity or the current time, which is the version almost every modern system actually wants. Toggle uppercase or remove dashes if your target system expects a different format, then copy individual values or everything at once.
Frequently asked questions
What kind of UUIDs does this generator create?
Version 4 UUIDs, which are built from random data rather than your device or the current time. This is the version most modern systems expect.
How many UUIDs can I generate at once?
Up to 100 at a time. You can copy individual values or everything at once.
Can I change the format?
Yes. Toggle uppercase or remove the dashes if your system expects a different format.
Is a UUID the same as a GUID?
Yes. GUID is simply the name Microsoft uses for a UUID, so the values from this tool work for both.
