Fair random numbers for any purpose
Set a minimum, a maximum, and how many numbers you need — with an option to forbid repeats for raffles and prize draws. Unlike simple generators, this one uses unbiased cryptographic sampling, so the edges of your range aren't subtly favored.
Frequently asked questions
How random are these numbers?
They come from your browser's cryptographic random number generator (the same source used for encryption keys), with rejection sampling so every value in your range is exactly equally likely.
What does “no repeats” do?
It draws without replacement, like pulling raffle tickets from a hat — each value appears at most once. Perfect for picking multiple distinct winners.
Can anyone predict or influence the result?
No. Numbers are generated on your device at the moment you click; there's no server, seed, or history involved.
