Generate random numbers with range and uniqueness control.
Generate random numbers within a custom range with options for count and uniqueness. This free, browser-based tool is perfect for lotteries, sampling, gaming, and any situation requiring unbiased random integers. No account or installation needed.
The Random Number Generator produces one or more random integers within a specified range. You define the minimum and maximum values along with how many numbers to generate in a single draw. An optional uniqueness constraint ensures no duplicates appear in the result set, which is essential for lottery-style draws or sampling. The tool uses the browser's built-in randomization capabilities to produce unbiased results. It runs entirely client-side, meaning your selections and configurations stay private on your device.
Set the Minimum and Maximum fields to define your desired range — for example, 1 to 100. Enter how many numbers you want in the "How Many" field. Check "Unique numbers only" if you need each result to be distinct. Click "Generate" to produce your random numbers instantly. The results appear on screen and can be regenerated with a single click. Use "Clear" to reset the output and start fresh with new parameters.
