UUID generator

Generate random version 4 UUIDs, one or a thousand at a time.

Runs in your browser. Your data is not uploaded or stored.

How to use it

  1. Choose your options above the result.
  2. A new set is made every time you change an option or press Generate.
  3. Copy the result or download it as a text file.

Good to know

  • UUIDs are made with your browser’s cryptographically secure random generator.
  • Version 4 UUIDs have 122 random bits, so the chance of two ever matching is negligible.

Questions

Is my data uploaded anywhere?
No. Everything runs in your browser with JavaScript. What you type or paste never leaves your device.
What is the difference between a UUID and a GUID?
They are the same thing. GUID is the name Microsoft uses for a UUID.

Every tool runs in your web browser. Text you paste and files you open are processed on your own device. We do not upload, store or sell them, and you do not need an account.

If you switch theme, that choice is saved in your browser so the site remembers it. Pages load fonts from Google Fonts, so your browser connects to Google’s servers to download them. We do not use advertising or tracking cookies; if that changes, this notice will be updated first.
