Generate random version-4 UUIDs in bulk.

Uses your browser's native crypto.randomUUID() — cryptographically strong identifiers, generated offline.

Frequently asked questions

What is a UUID used for?

As a practically collision-free identifier for database records, API objects, filenames and distributed systems.

Can two generated UUIDs collide?

The probability is so small it is negligible in practice — you would need to generate billions per second for centuries.
