About UUID Generator
Generate RFC 4122 version 4 UUIDs, one at a time or in bulk. Press Generate to see the result in the results panel. Everything runs locally in your browser; nothing is uploaded. Only the current result is shown — no history or side-by-side comparison.
UUID Generator reads "How many" and "Case" from the form above and writes the answer into the results panel. There is no account, no upload and no server round-trip: the JavaScript on this page does the work on your own device.
How to use UUID Generator
- Open UUID Generator from Generators & Utilities, or find it with the search box in the header.
- Fill in the fields shown above: "How many" and "Case".
- Press Generate. The result replaces whatever was shown before; only the current run is displayed, never two results side by side.
- Use Copy all to put the result on your clipboard. A message appears only when something was actually copied.
A worked example
The form opens with these values: How many = 5. Press Generate once to see how the output is laid out, then replace them with your own data and press again — the new result replaces the old one.
Frequently asked questions
Is what I type uploaded anywhere?
No. UUID Generator processes "How many" and "Case" with JavaScript inside your browser. Your inputs and the result stay on your device; Utilixo keeps no copy of them.
Can I keep several results to compare?
No. Each press of Generate rebuilds the result from the current inputs and overwrites the previous one. To compare runs, note the earlier result down yourself.
Anything specific to watch with UUID Generator?
The result depends only on the fields shown above ("How many" and "Case"); change one of them and press Generate again to get an updated answer.
How do I take the result away?
Press Copy all after a result appears. The copy button only reports success when there is content to copy.
Do I need to sign up or pay?
No. UUID Generator is free, needs no registration and has no usage limit. Open the page and use it.
