Any range, any count, with or without repeats.

Fromto How many

No repeats Order

Set a range and press Generate.

Each press uses a new seed from your browser’s cryptographic random numbers. Nothing is sent anywhere. See how picks are made

How to use it

Set the lowest and highest number, both included, and how many you want. Tick No repeats to get different numbers every time; the range must then hold at least that many numbers. Results can stay in the order drawn or be sorted.

How the numbers are made

Each press makes a new seed from your browser’s cryptographic random numbers. Whole numbers are taken by drawing only as many random bits as the range needs and throwing away any value that falls outside it. That avoids the small bias of dividing and taking the remainder, so every number in the range is equally likely.

Limits

Whole numbers only, up to 15 digits (from −999,999,999,999,999 to 999,999,999,999,999), and up to 10,000 numbers at a time. Inputs outside those limits show a message instead of a wrong answer.

Questions

Can I get 1 to 100 with no repeats?

Yes. Set 1 and 100, choose how many, and tick No repeats. You can ask for at most 100 in that range.

Is it suitable for passwords or keys?

No. It is made for draws, games and choosing at random. Use a password manager to create passwords and keys.
