UUID Generator
Generate random UUIDs (Universally Unique Identifiers) v4. Click generate or customize the output.
Why Use a UUID
A UUID v4 is a 128-bit identifier generated with enough randomness that collisions are practically impossible for normal use. Developers use them for database keys, client-generated IDs, tracking events, and test data when they need an identifier that does not depend on a central counter.
Tips for Bulk Generation
- Generate 1, 10, or 100 IDs depending on your task
- Use one ID per line when you need to paste them into a spreadsheet
- Remember that UUIDs are unique, not secret, so do not use them as security tokens
Are generated IDs stored anywhere?
No. The IDs are created locally in your browser and are not sent to a server.
