Random Number Generator
Generate random numbers for free — pick a range, how many numbers, whether repeats are allowed and whether to sort them. Roll any number of dice, flip coins, or pick winners from a list of names. Numbers come from your browser's cryptographically secure generator, with no bias.
100% private — everything runs in your browser. Conversion happens on your device; nothing is uploaded.
Numbers come from your browser’s cryptographically secure random generator (crypto.getRandomValues) with unbiased rejection sampling, so every value in the range is equally likely. Fine for games, raffles and sampling — not a substitute for audited systems in regulated lotteries.

Are the numbers truly random?
They come from crypto.getRandomValues, the same secure generator used for encryption keys, with rejection sampling so every number in the range is equally likely.
How do I get numbers without repeats?
Tick “No repeats”. You can't ask for more unique numbers than the range contains.
Can I pick a random name?
Yes — choose “Pick from a list”, enter one name per line, and choose how many winners.
