How Random Is It?
Numbers come from Math.random, which produces a uniform distribution suitable for games, draws, sampling, and everyday randomness. It is not cryptographically secure, so for passwords, tokens, or anything security-sensitive use the Password Generator instead.
Frequently Asked Questions
How do I generate a random number?
Set a minimum and maximum, choose how many numbers you want, and click Generate. Each result is a random whole number within your range, inclusive of both ends.
Can I generate more than one number at once?
Yes. Enter how many numbers you need (up to 1,000) and they are all generated together, then you can copy the whole list with the Copy button.
Can I use a custom range, including negatives?
Yes. Set any minimum and maximum, including negative numbers — for example -10 to 10. The generator returns whole numbers within the range you choose.
Can the same number appear more than once?
Yes. Each number is drawn independently, so repeats are possible when generating several. If you need unique results with no repeats, use the Random Picker to draw from a list instead.
Is this random number generator secure enough for passwords?
It uses your browser's built-in Math.random, which is uniform and great for everyday needs like draws, games, and sampling — but it is not cryptographically secure. For passwords or security tokens, use the Password Generator instead.
