Tip: press Space to generate, C to copy.
Pull a true number the instant you need one. It returns a uniformly random number across whatever range you set — no patterns, no repeats unless you allow them. Useful for raffles, testing, sampling, and fair decisions.
Truly random numbers matter more than people expect — for fair draws, unbiased sampling and quick test data. This true number generator uses your browser's cryptographic random source, so results aren't the predictable pseudo-random sequences some simple tools produce.
Example true numbers you might get
A few true numbers this generator can land on: 44, 6, 63, 11, 40, 62, 69, 60, 58, 18.
How the True Random Number Generator works
Enter a minimum and maximum, choose how many values you want, and the generator returns uniformly distributed numbers from your browser's cryptographic RNG. Flip on unique to guarantee no duplicates within a draw.
Ways to use it
- Use the true number generator to run a fair raffle or giveaway draw.
- Use the true number generator to break a decision deadlock when every option looks the same.
- Use the true number generator to draw lottery-style numbers.
- Use the true number generator to assign anonymous IDs fairly.
Tips for better results
- Turn on the no-repeats option when you want a unique set rather than independent draws.
- Generate a batch and shortlist the results you like instead of taking the first one.
- Use unique mode for lottery-style draws with no duplicates.
Frequently asked questions
Can I avoid duplicate numbers?
Yes, enable unique and a single draw will contain no repeats.
Is this suitable for raffles or sampling?
It's great for casual raffles and sampling. For regulated draws, pair it with a documented procedure.
Does it work on mobile?
It does — the generator is fully responsive and works the same on phones, tablets, and desktops.
Are the numbers cryptographically random?
They use the browser's crypto RNG, which is far stronger than typical pseudo-random functions — suitable for fair draws and sampling.
