UUID Generator

Generate unique identifiers (UUID v1, v4, v5, v7) for databases and APIs.

Tip: UUID v7 is recommended for database IDs as they're lexicographically sortable by creation time.

FAQ

Is this UUID generator free?

Yes, and all generation happens locally in your browser using crypto.getRandomValues().

Which UUID version should I use?

v4 for randomness, v7 for time-sorted IDs, v5 for name-based UUIDs.

Can I generate multiple UUIDs at once?

Yes, bulk generation supports up to 1000 UUIDs in a single click.

How To Use It

UUID Versions: When to Use Which

v4 is the most common — completely random and simple.

v7 includes a timestamp, useful for sorting by creation time.

What Makes a UUID Unique?

122 random bits make collisions astronomically unlikely for v4.

You'll never accidentally generate the same UUID twice in practice.
