About the UUID Generator
A UUID (Universally Unique Identifier), also called a GUID, is a 128-bit value used to uniquely identify records, files or objects without a central authority. Version 4 UUIDs are generated from random numbers, making collisions astronomically unlikely.
This tool generates version-4 UUIDs using the browser’s secure random number generator, so they are suitable for database keys, request IDs and more. Everything happens locally in your browser.
Frequently asked questions
Are these UUIDs unique?
Version-4 UUIDs are random 128-bit values; the chance of a collision is negligible for virtually any real-world use.
Is a UUID the same as a GUID?
Yes — GUID is Microsoft’s name for the same 128-bit identifier standard.
