UUID Generator — free online tool
You're building something and you need a unique ID. Maybe a few, maybe a few hundred. Typing random characters by hand is a pain, and it's easy to accidentally repeat one. We added a free tool that does it for you — UUID Generator — right in your browser.
What it does
It generates version 4 UUIDs, the random kind. You can make one at a time or a whole batch at once, then copy the list straight out. That's the whole job: clean, ready-to-use IDs whenever you need them.
Nothing leaves your device
The tool runs entirely in your browser. The IDs are made right there on your computer, so nothing is uploaded and nothing is saved on a server. When you close the page, it's all gone.
How to use it
- Open UUID Generator.
- Choose how many UUIDs you want and generate them.
- Copy the result and paste it wherever you need it.
It's free with no limit. There are more small tools on the Apps page.
