How UUID Generator works

Step 01

Set the count

Pick anywhere from 1 to 500 UUIDs at once — perfect for seeding a database or bulk-generating test records.

Step 02

Generate

We call crypto.randomUUID() — the browser's cryptographically-secure RFC 4122 v4 generator.

Step 03

Copy individually or in bulk

One-click copy per row or copy the entire list as newline-separated text.

FAQ

What flavour of UUID is this?+

UUID v4 — pseudo-random, 122 bits of entropy per ID. The collision probability is effectively zero for real-world scales.

Is this suitable for production keys?+

Yes — crypto.randomUUID() is the same primitive used by wallets, password managers and modern databases (Postgres 13+, MongoDB, etc).

Any browser compatibility issues?+

crypto.randomUUID() is supported in every modern browser (Chrome 92+, Firefox 95+, Safari 15.4+, Edge 92+).
