Random Number Generator

Overview

What is a Random Number Generator?

Random Number Generator picks random numbers in a range you set. Choose the minimum and maximum, how many numbers you want, and whether they must be unique — and it generates them with a secure random generator, right in your browser. Copy or download the results.

Picking a random number is the most basic randomizer of all — for raffles, games, sampling, decisions, or test data. This tool generates one number or many within whatever range you choose, fairly and instantly.

It runs entirely in your browser using a secure random generator, so the numbers are genuinely unpredictable and nothing is uploaded. Set the range and count, choose unique or repeatable, and generate.

Range, uniqueness, and fairness

The generator picks uniformly across your range with both ends included, using your browser's secure random generator, so every number in range is equally likely and the result is genuinely unpredictable. Choose 'unique' when you need distinct numbers (like drawing raffle tickets) — that's capped by the size of the range, since you can't draw more unique numbers than exist. Allow repeats when each pick is independent (like rolling the same die repeatedly). For decimals, set a range and precision. Everything runs locally, so it's instant and private. For game-specific draws use the Lottery Number Generator or Bingo caller; for dice, the Dice Roller.

Frequently Asked Questions

How do I generate a random number in a range?

Enter the minimum and maximum, then generate — you get a random number with both ends of the range included. Set the count to generate several at once, and choose whether they should be unique. Every number in the range has an equal chance.

Can I generate several numbers at once?

Yes. Set the count to produce a list of random numbers in one go, with the option to require them to be unique (no repeats) or allow repeats. Unique mode is great for draws; repeatable mode suits independent picks like repeated rolls.

Is the randomness fair and secure?

Yes. It uses your browser's cryptographically secure random number generator, so each number is genuinely unpredictable and uniformly distributed across the range — not biased toward the middle or ends. That makes it suitable for raffles and fair selection, not just casual use.

Can it include negative numbers or decimals?

Yes. The range can span negative and positive numbers, and a decimals option lets you generate fractional numbers with a chosen precision. Set the min, max, and precision to match what you need, whether that's a percentage, a measurement, or a whole number.

Can I draw unique numbers with no repeats?

Yes. Turn on the unique option and the generated numbers won't repeat — ideal for raffles, sampling, or assigning IDs. The number you can draw is capped by the size of the range, since there can't be more unique values than the range contains.

Is anything uploaded?

No. Numbers are generated entirely in your browser, so nothing is uploaded or stored, and it works offline once the page has loaded. You can generate random numbers privately and instantly without an account.

Is it private — is anything uploaded?

No. Everything runs in your browser, so whatever you enter is processed on your own device and never uploaded. Nothing is stored once you close the tab unless you choose to save it. That keeps your lists, names, and data private.

Is it free, and do I need to sign up?

Yes, it's completely free with no account, no trial, and no limit on how many times you use it. Because it runs entirely in your browser, there are no server costs, no usage caps, and no watermark or branding added to your result.

Does it work on a phone?

Yes. It runs in your phone's browser with nothing to install, so you can use it on Android or iOS. The layout adapts to small screens, making it easy to use on the go, at a party, or in a classroom.

Does it work offline?

Once the page has loaded, it runs entirely on your device, so it keeps working without a connection — which is also why nothing is uploaded. You only need to be online to open the page the first time; after that the tool works locally.

Can I copy or share the result?

Yes. You can copy the result to your clipboard with one click, and many results can be downloaded or shared. Everything is generated locally, so copying and sharing are instant with no upload step.

Is the randomness fair?

Yes. The tool uses your browser's secure random number generator, so every outcome is genuinely unpredictable and each option has an equal chance. It isn't weighted or rigged — results are as fair as a well-shuffled deck or an even spin.
