Random Number Generator

You set a low and a high number, choose how many you want, and it draws them from your browser's cryptographic random source, which has no predictable pattern. The range includes both ends, so 1 to 100 can return 1 or 100. It all runs on your device, so nothing you generate is sent anywhere, and you'll get a fresh set every time you press the button.

It uses the browser's crypto random source, which is built for unpredictability and is far stronger than the basic random function used in many scripts. For a raffle, a game, or picking a sample, it's as good as you need. True physical randomness comes from hardware, but for everyday picks this is indistinguishable from it.

Turn on the no-repeats option and each number in the set is unique, like drawing names from a hat. That only works when you ask for no more numbers than the range holds, so a 1-to-10 range can give at most 10 unique values. With repeats allowed, every draw is independent, so the same number can show up more than once.

Yes, set the count to 1 and you'll get one number in your range, which is the most common use, like a quick dice roll or a coin-flip stand-in. Bump the count up for a list, such as lottery-style picks or a set of test values. The result shows them together, and you can copy the whole list at once.

Whatever fits the task. Use 1 to 6 for a die, 1 to 2 for a coin, 1 to 100 for a percentage-style pick, or any custom span for a giveaway. Negative numbers work too, so a range like negative 10 to 10 is fine. The generator handles any whole-number range as long as the high value is not below the low one.

Yes to both. There's no sign-up, no limit, and nothing to install, since it runs in your browser. Nothing you generate is logged or sent to a server. Bookmark it for raffles, games, classroom picks, or testing, and you'll have a quick, fair random draw whenever you need one.
