About the uuid generator
UUID Generator is a free online tool that lets you generate cryptographically random UUID v4 identifiers in seconds. Everything happens locally inside your browser, so your files and text never leave your device and nothing is ever uploaded to a server. That makes it a safe choice for private, sensitive or work documents — and it also means the tool stays fast even on a phone or a slow connection. There is no account to create, no email to hand over, no daily limit and no watermark on anything you produce. It's built for developers, designers and curious tinkerers who need a reliable result right now, then want to get on with their day.

- 2. Adjust the options if you want a different result.
- 3. Press “Generate” — processing happens on your device.
