Random Number Generator

About Random Number Generator

A random number generator picks numbers at random within a range you choose. Set a minimum and maximum — negatives are fine — pick how many you want, and optionally make them unique (no repeats) or sorted. It's handy for draws, sampling, games, and picking any number between two values. Everything runs in your browser using its built-in randomness.

Frequently asked questions

How do I generate a random number between 1 and 100?

Set Min to 1 and Max to 100, leave the count at 1, and hit Generate. You can use any whole-number range — including negatives — just change the min and max.

How do I get random numbers with no repeats?

Turn on 'Unique (no repeats)'. If you request more numbers than the range can hold, you'll simply get every value in the range once. Add 'Sort ascending' to get them in order.

How many numbers can I generate at once?

Up to 10,000 in a single click. They're shown as a comma-separated list you can copy, or as one large number when you generate just one.

Are the numbers truly random?

They use your browser's built-in random number generator — high-quality pseudo-randomness that's more than enough for games, draws, and picking a winner, though it isn't certified for cryptographic or lottery use.
