Random Number Generator — FAQs
How are the random numbers produced?
Numbers are generated in your browser using the operating system's cryptographically secure random source (crypto.getRandomValues), not a weak pseudo-random formula. Each integer in your chosen range has an equal probability, so draws are fair for raffles, games and sampling. No data is sent anywhere — the computation happens entirely on your device.
What does unique-only mode do?
Unique-only mode guarantees that no number appears twice in your list, which is exactly what you need for lottery-style draws, prize raffles and random sampling without replacement. If you ask for more unique numbers than the range contains, the tool warns you instead of failing, so you can widen the range or lower the count.
Can I generate decimal numbers?
This tool generates whole integers only, which covers raffles, dice-style draws, PIN ideas and sampling. If you need decimals, you can divide the results yourself — for example, generate numbers between 0 and 1000 and divide by 1000 for three-decimal random fractions. Keeping integers makes fair draws and copy-paste lists simple.
Is my input sent to a server?
No. Everything runs locally in your browser with zero network requests, no account and no logging. Your ranges, counts and results stay on your own device, so the tool is safe to use on any computer or phone, even offline once the page has loaded.
