Generate random numbers in a range
This tool generates random whole numbers in a range you set, using your browser's secure random source. Make a single number for a dice roll or a coin toss, or many at once, with an option to make every value unique, which is useful for lottery draws or picking winners.
How to generate random numbers
Set the minimum and maximum, choose how many numbers and whether they must be unique, and click Generate.
Frequently asked questions
Are the numbers really random?
They use the browser's secure random generator, which is far stronger than the typical pseudo-random function.
Why can't I get more unique numbers than the range holds?
If you ask for ten unique numbers between one and five, there simply are not enough distinct values, so the tool tells you instead of repeating any.
