About this tool

Random Number Generator picks whole numbers between the limits you set, both included. It uses the browser’s cryptographic random source, so every number in the range has the same chance, which makes it fair for draws, games and sampling.

How to use Random Number Generator

  1. Enter the minimum, the maximum and how many numbers you need.
  2. Tick No repeats or Sort if you want them.
  3. Press Generate and copy the results.

Questions people ask

Are the numbers truly random?

They come from crypto.getRandomValues, the same secure source used for passwords. The tool also uses rejection sampling, so there is no bias toward any number.

Are the minimum and maximum included?

Yes. A range of 1 to 6 can return 1, 2, 3, 4, 5 or 6.

How many unique numbers can I pick?

Up to the size of the range. Between 1 and 50 you can pick at most 50 numbers with no repeats, and up to 10,000 numbers per run.
