Random Number Generator

This free random number generator produces one or many random numbers in any range you choose, instantly and fairly. Set a minimum and maximum, say how many numbers you need, decide whether duplicates are allowed, and click Generate. Behind the scenes it uses the cryptographically secure random source built into your browser, the same quality of randomness used in encryption. That makes it far more trustworthy than a spreadsheet formula or someone shouting a number from the back of the room. Whether you are running a giveaway, drawing raffle winners, assigning teams or sampling survey responses, this number picker gives every value in the range an equal chance, and it does it all on your device.

How to use

1. Enter the minimum and maximum values of your range, for example 1 to 100, or 1 to the number of raffle tickets sold.
2. Choose how many numbers you want to generate at once.
3. Decide whether duplicates are allowed. Untick 'Allow duplicates' for prize draws so no ticket can win twice.
4. Click Generate and your numbers appear instantly.
5. Click Copy to grab the results for a spreadsheet, an announcement post or your records.
6. For a public draw, consider screen recording the moment you generate, so participants can see the result was produced live.

Why use our random number generator?

Fairness is the whole point of a random draw, and fairness depends on the quality of the randomness. This generator uses the browser's cryptographic random source rather than a basic formula, so results are statistically unbiased and every number in your range has an exactly equal chance. The no-duplicates mode also does the bookkeeping a manual draw gets wrong: once a number is drawn, it cannot come up again.

It is quick for real work too. Generate a hundred sample IDs in one click and paste them straight into a spreadsheet. Everything runs locally, so nothing about your draw is sent anywhere. If your giveaway needs supporting tools, they are one click away. Announce winners with a scannable link from the QR code generator, count down to the draw date with the date difference calculator, or set up a prize account with the password generator.

Who is this tool for?

Social media managers and small businesses use it for giveaway draws: number the entrants, generate one winner, screenshot the result. Raffle organizers at schools, clubs and charities draw ticket numbers without pulling paper from a hat. Teachers pick a random student for a question, set presentation order, or split a class into random groups. With duplicates off, everyone gets picked exactly once.

Researchers use random numbers for sampling, like choosing which 50 of 800 survey responses to audit, and for splitting participants into test groups. Game nights use it as a giant dice roller when the real dice have gone missing. Sports coaches draw fixtures and knockout brackets with it. Developers generate quick test IDs during development. Any decision that should be visibly fair is a job for this tool.
