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.
