Random Number Generator: Pick Numbers Instantly
This free random number generator picks numbers in any range you set — one number or up to 100 at once, with optional unique (no repeats) and sorted output. Raffles, samples, passwords-with-digits, classroom picks — done in one click.
How to generate numbers
- Set your range — minimum and maximum (they can be negative, and min/max auto-swap if reversed).
- Choose how many — 1 for a single pick, up to 100 for a full set.
- Tick options: Unique guarantees no repeats; Sort orders the results.
- Generate. Done — again and again, free.
When to use "unique"
- Raffles & draws: unique numbers mean no ticket wins twice.
- Lottery-style picks: real lotteries never repeat a main number — unique + sorted mimics a real ticket line.
- Sampling: pick 10 unique students from a class list numbered 1–30.
- Leave it off for dice-style rolls, where repeats are natural (two dice can both show 4).
True randomness is a deep topic — computers use special algorithms or hardware for it. Ours uses your browser's cryptographic RNG; for the full story see Wikipedia on random number generation.
What people generate numbers for
- Giveaways: pick a winning comment or ticket number transparently.
- Teachers: random student picker, random groups, random quiz questions.
- Games: bingo-style draws, guessing games ("I'm thinking of a number…"), RPG tables.
- Research: random sampling for surveys and experiments.
- Passwords & PINs: a random 6-digit number makes a decent PIN (but use our Password Generator for real security).
Random vs. pseudorandom: what this tool actually does
No everyday computer generates "true" randomness from nothing — most use a pseudorandom number generator (PRNG), an algorithm whose output passes statistical tests for unpredictability. This page goes further: it draws from your browser's cryptographic RNG — the same entropy source behind secure tokens and encryption keys — so every number in your range has an exactly equal chance on every draw.
Draws never influence each other, and no pattern emerges no matter how many thousands you generate. That's overkill for picking a raffle winner — and exactly right for it. Teachers can generate 100 numbers and watch the distribution flatten out; giveaway hosts can pair a draw with the Random Winner Picker for name-based contests, or try the Lottery Number Generator for ticket-style picks.
Number Generator FAQs
Are the numbers truly random?
Yes — drawn from your browser's cryptographic random number generator. Every number in your range is equally likely on every draw.
What's the biggest range?
Any integers your browser can handle — negatives included. Generate up to 100 numbers per click.
Why did I get an error about unique numbers?
Unique mode can't return more numbers than exist in your range — e.g. max 10 unique numbers between 1 and 10. Widen the range or lower the count.
Can I generate decimals?
This tool generates whole numbers only — decimals rarely matter for picks and draws.
Does it store my numbers?
Never — everything happens in your tab (Privacy Policy).
Is it free?
Completely — unlimited generation, no account, no sign-up.
