How to use the random number generator
Need a random number for a game, a raffle, a classroom activity or a decision? This tool generates random numbers instantly, or picks random winners from a list of names.
Generating numbers
- Enter a minimum and maximum.
- Choose how many numbers you want, and how many decimal places (0 for whole numbers).
- Tick No repeats if each number should appear only once, and Sort if you want them in order.
- Press Generate. Press it again for a fresh set.
Picking from a list
Switch to Pick from a list, paste your names or items (one per line or separated by commas), choose how many to pick, and press Generate. Picks are shown in random order, which is handy for choosing a winner and runners-up.
Is it truly random?
This tool uses your browser's cryptographically secure random number generator (the Web Crypto API), the same kind of randomness used for security purposes. It's far less predictable than the basic random functions found in many simple tools. It also uses a technique called rejection sampling, so every number in your range has an equal chance of being chosen.
Everything runs on your device, so the numbers and lists you enter are never sent anywhere.

With or without repeats
No repeats works like drawing numbered balls from a bag without putting them back, so each number can appear only once. This is what you want for raffles, lotteries and choosing people. Without this option, each number is chosen independently, like rolling a die several times, so the same number can come up more than once.
If you ask for more unique numbers than exist in your range, such as 11 different numbers between 1 and 10, the tool will tell you it isn't possible.
Tips for fair draws
- Decide the rules first, such as the range and how many winners, before you generate.
- Use one draw. Redrawing until you get a result you like isn't random.
- Share your screen or record the draw if you're running a public giveaway, for transparency.
- Check local rules for official prize draws or lotteries, which may have legal requirements.
