Random Number Generator

Generate one or many random numbers in any range — instantly, with an option for unique results.

Set a range and press Generate.

How to use the random number generator

  • Set the minimum and maximum of your range.
  • Choose how many numbers you want, and tick no repeats for unique values (great for raffles and draws).
  • Press Generate — results appear instantly and you can copy them.

What it's good for

Random numbers are handy for giveaways and prize draws, picking a winner, choosing who goes first, sampling, games, lottery-style number picks, or any decision you want to leave to chance. It uses your browser's random function, runs on your device, and never uploads anything.

Benefits

  • Generates one or many random numbers in any range instantly.
  • Optional "no repeats" mode for unique picks — ideal for raffles and draws.
  • Runs in your browser; nothing is stored or uploaded.
  • Free and unlimited.

Limitations to know

  • It uses the browser’s standard random function — plenty random for draws and games, but not intended for cryptographic use.
  • For unique results, the count can’t exceed the size of the range.
  • It produces whole numbers within your min–max range.

Common mistakes to avoid

  • Requesting more unique numbers than the range allows.
  • Swapping min and max (the tool corrects it, but check your range).
  • Using it where a cryptographically secure random source is genuinely required.

Alternatives

For secure passwords use the Password Generator; for unique IDs use the UUID Generator.

Frequently asked questions

Are the numbers truly random?

They use the browser's built-in random generator, which is more than random enough for draws, games and everyday use.

Can I get unique numbers with no repeats?

Yes — tick "no repeats." Just make sure your range is at least as large as the count you request.

Is anything stored or uploaded?

No. Everything runs in your browser.
