A UUID generator creates unique IDs from random bits. Each ID looks like a long string of letters and numbers split by dashes. They help rows and files avoid name clashes.
Pick how many IDs you need, copy the full list, and paste into your database seed, API test, or config. The UUID generator runs locally with crypto-grade randomness.
Use this UUID generator when you need a quick batch without installing tools. Refresh for more IDs anytime. No account and no server upload.

Common questions
What is a UUID generator?
It makes long random IDs that almost never repeat. Apps use them as keys in databases, APIs, and file names.
How many IDs can this UUID generator make at once?
Up to 50 per click. Hit Again for another batch. All IDs are made on your device.
Is this UUID generator the same as a GUID?
Yes. GUID and UUID mean the same kind of unique ID. This tool outputs standard UUID v4 values.
Does the UUID generator send my IDs to a server?
No. IDs are built with the browser crypto API. Nothing is uploaded.
When should I use a UUID generator?
When you need test keys, sample API payloads, or file names without opening a terminal or script.
