Frequently Asked Questions

Are the generated numbers truly random?

This online tool uses your browser's built-in pseudo-random number generator (`Math.random()`). While it is excellent for most common purposes like games, contests, or simulations, it is not considered cryptographically secure and should not be used for high-security applications like encryption keys.

Is this random number generator free?

Yes, this is a completely free online tool. You can generate as many random numbers as you need.

What happens if I ask for more unique numbers than are available in the range?

If you turn off 'Allow Duplicates' and request more numbers than are possible (e.g., asking for 10 unique numbers between 1 and 5), the generator will simply return an empty result set.
