UUID Generator

Create one or many version-4 UUIDs using the browser’s secure random source. Bulk generate, choose casing, and copy the whole list at once.

Examples

Input

count = 1

Output

3f50b1c2-9a7e-4f3a-8b21-77c0d1e2f3a4

How it works

Every UUID here is version 4: 122 random bits taken from the browser’s cryptographic random generator, plus six fixed bits that mark the version and variant.

xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

4 = the version
y = 8, 9, a or b (the variant)

You can generate from 1 to 1,000 at a time, one per line, in lower or upper case. A version 4 UUID holds no timestamp and no device information, so it says nothing about when or where it was made, and a list of them does not sort by creation time.

How to use UUID Generator

Set the count

Pick how many UUIDs you need (1–1000).

Generate

Click Generate to create cryptographically random v4 UUIDs.

Copy

Copy a single value or the entire list.

Why use this tool

Cryptographically secure (crypto.randomUUID)

Bulk generation up to 1000

Uppercase / lowercase

No collisions in practice

Frequently asked questions

Are these UUIDs unique?

They are version-4 UUIDs with 122 random bits, generated from a secure source. The chance of a collision is astronomically small.
