Frequently asked questions
How random are these numbers?
They're generated using your browser's cryptographically secure random number generator, the same source used for passwords and UUIDs on this site.
What happens if I ask for more unique numbers than the range allows?
The tool shows an error rather than silently generating duplicates — for example, you can't get 20 unique numbers from a range of only 10.
