Common questions

Is this random number generator truly random?

It uses your browser's cryptographic random source, the one used for encryption keys, and removes the small bias the usual remainder shortcut adds, so every value in the range is equally likely.

How do I get numbers without repeats?

Leave No repeats ticked. If you ask for more numbers than the range holds, such as 11 different numbers from 1 to 10, the page tells you how many fit.

Can I pick a giveaway winner?

Yes. Choose Pick from a list, paste one entrant per line and click Pick. Each name is equally likely, and picking several gives different people.

Can it split people into teams?

Yes. Paste the names, choose the number of teams and click Pick; the list is shuffled and dealt out so team sizes differ by at most one.

Can I generate decimals?

Yes, with up to three decimals. With 2 decimals, 0 to 1 gives values like 0.37.

Are the results saved?

No. Nothing is stored or sent; copy the result or take a screenshot if you need a record.

Is it free?

Yes, completely free, with no sign-up.
