How to use UUID Generator

Choose single or bulk mode and how many you need, and the tool generates RFC 4122 version 4 UUIDs with one click to copy one or the whole list.

Frequently asked questions

Are these UUIDs guaranteed unique?

They're version 4 (random) UUIDs — the chance of a collision is astronomically small (about 1 in 5.3×10^36), which is why they're used as database primary keys.

Is this tool free to use?

Yes. This tool is completely free to use with no daily limits and no signup required.

Can I generate more than one at a time?

Most ID generators here support a bulk mode — set the count and copy the whole list at once.
