UUID / GUID v4 Generator

A UUID (universally unique identifier) is a 128-bit value used to identify records without a central authority assigning them — common for database primary keys, API request IDs, and JWT jti claims. This tool generates cryptographically random v4 UUIDs, individually or in bulk.

Frequently Asked Questions

How unlikely is a UUID collision?: For v4 UUIDs, the odds are astronomically low — effectively negligible for any realistic application.
Can I generate multiple UUIDs at once?: Yes, specify how many and get a bulk list.
