Random Number Generator

Pick a random number between 1 and 100, draw lottery-style numbers without repeats, or generate thousands at once. Results come from a cryptographically secure source, so they cannot be predicted.

Lottery-style draw. Min 1, max 49, 6 numbers, no repeats, sorted.

Pick a winner. Min 1, max 250 (the number of entries), 1 number.

Frequently asked questions

Are the numbers truly random?

They come from crypto.getRandomValues, the browser's cryptographically secure generator, and rejection sampling removes any bias, so every number in the range is equally likely.

Can I use it for a raffle or giveaway?

Yes. Number the entries, set the range and draw. For names instead of numbers, use the Random Picker.

Is anything sent to a server?

No. Numbers are generated in your browser.
