Generate a UUID instantly — paste it into your code, your database, your config file, and move on. Choose between Version 4 (purely random) or Version 1 (time-based), switch between uppercase and lowercase, strip the hyphens if your system needs a plain 32-character string, or generate up to 100 at a time in batch mode. Each UUID is generated locally in your browser using cryptographically secure randomness — nothing is sent to any server.

No ads. No fees. No signup. Just a tool that works.
