Random Number Generator
Free online random number generator. Set a minimum, maximum, and how many numbers you want, with an option to allow or forbid duplicates.
A random number generator produces unpredictable integers within a range you define. Set a minimum and maximum, choose how many numbers you need, and generate a fair draw — useful for raffles, picking winners, sampling, games, or any time you need an impartial number on demand.
Switch off "allow duplicates" when every number must be unique, like drawing lottery numbers or assigning slots. The generator draws without repeats and tells you if the range is too small to fill your request, so you never get a silent or impossible result. Everything runs locally in your browser.
Frequently asked questions
Are the minimum and maximum included?
Yes. Generated numbers can be anywhere from the minimum to the maximum, with both endpoints possible.
What does 'allow duplicates' do?
When checked, the same number can appear more than once. When unchecked, every generated number is unique.
What if the range is too small for unique numbers?
If you ask for more unique numbers than the range contains, the tool tells you instead of looping forever. Widen the range or reduce the count.
Is anything sent to a server?
No. All numbers are generated in your browser and never leave your device.
