Random Number Generator

Looking for a random number generator between two numbers? This free tool gives you fair random whole numbers in any range, as many as you need. Just enter your numbers and press Calculate — results are instant.

How to Use This Random Number Generator

This tool draws whole numbers at random from the range you set, minimum to maximum inclusive, using the random number generator built into your browser. Each number is drawn independently, so repeats are possible, and every press of the button makes a completely fresh set. It is fair enough for draws, games and picking things at random; it is not meant for security or cryptography, where a special cryptographic generator is needed.

Formula Used

Each number is drawn independently and uniformly from your range, minimum to maximum inclusive, using the browser's built-in random number generator. Every press makes a fresh set.

Worked Example

Example: Minimum 1 · Maximum 100 · How many: 5

  1. Each number is drawn independently from 1 to 100 inclusive.
  2. One run produced: 63, 48, 33, 95, 35.
  3. Press Calculate again and you get a completely different set — repeats are possible, because every draw is independent.

Generated Numbers: 63, 48, 33, 95, 35

Frequently Asked Questions

Are the numbers truly random?

They come from the random number generator built into your browser, which is fair enough for draws, games and picking things at random. It is not the cryptographic kind used for security, so do not use it for passwords or secrets.

Can the same number come up twice?

Yes. Each draw is independent, so repeats are possible and expected — getting the same number twice does not mean the generator is broken.

Why would I need random numbers?

For raffles and draws, for picking teams or winners, for games, for sampling data, or for any time a fair, unbiased pick is needed.
