Frequently Asked Questions
How do I pick a random number between 1 and 100?
Set the minimum to 1 and maximum to 100, keep the count at 1, and click Generate. The tool uses cryptographic randomness to ensure a fair, unbiased result.
Can I generate unique random numbers (no repeats)?
Yes. Enable the 'Unique only' toggle before generating. This ensures every generated number appears only once in the list. Note that you cannot generate more unique numbers than the size of your range.
How do I use this for a lottery or giveaway?
Enter the range of your participants (e.g. 1 to 500), set the count to how many winners you need, enable 'Unique only' to prevent duplicate winners, and click Generate. The results are unbiased and random.
Can I generate random decimal numbers?
Yes. Set the 'Decimal Places' field to the number of decimal digits you want (1–10). For example, with min=0, max=1, and 2 decimal places, you will get numbers like 0.47 or 0.83.
