Random Number Generator Frequently asked questions

How random is this really?

Every number comes from crypto.getRandomValues, the operating system's cryptographically secure random source, with rejection sampling to remove modulo bias. That is the same source used for password and key generation, far stronger than Math.random.

What happens if I ask for more unique numbers than the range holds?

You get a clear message instead of bad output. For example, asking for 10 unique numbers between 1 and 5 is impossible, so the tool asks you to widen the range or allow duplicates.

Can I use this for a raffle or giveaway?

For informal draws among friends, clubs or classrooms, yes. For regulated lotteries or gambling, no: those need certified, audited systems and often witnessed draws.

How large a range can I use?

Any range that fits in a 32-bit integer, roughly from -2.1 billion to +2.1 billion. That covers practically any everyday need.

Are the results sent anywhere?

No. Generation happens entirely in your browser. Nothing is logged, stored or transmitted.
