UUID generator

About this tool

Choose version 4 or 7, how many you need and the notation, then copy the list. Version 4 is purely random. Version 7 starts with the current time, so newer IDs sort after older ones, which is gentler on database indexes. All values come from the secure random generator of your browser.

Good to know

Collisions are practically impossible for both versions. A UUID is an identifier, not a secret: do not use it as a password or access token.
