Frequently asked questions
- What is a UUID v4?
- A UUID v4 is a 128-bit identifier built mostly from random data. Its randomness makes accidental duplicates extremely unlikely, which is why it is widely used as a unique key.
- Are the UUIDs generated on a server?
- No. They are created locally in your browser, so nothing is sent over the network and the values stay private to you.
- Can two generated UUIDs ever collide?
- In theory yes, but the odds are so astronomically small that for practical purposes you can treat each version 4 UUID as unique.
- Can I generate UUIDs in bulk?
- Yes. Set the count to however many you need and use Copy all to paste the full list into your code or spreadsheet at once.
