Your random numbers
Numbers are generated with your browser's built-in random number source. They are fine for games, raffles, classroom picks and everyday decisions — but not for cryptography or gambling, which need a cryptographically secure source.
How to use
- Enter the minimum and maximum values for your range.
- Choose how many numbers to generate, and tick “No repeats” if every number must be unique.
- Click Generate Numbers — click again for a fresh set.
Frequently asked questions
Are the numbers truly random?
They come from your browser's Math.random() source, which is random enough for games, draws, lotteries and classroom use. It is not suitable for cryptography or real-money gambling.
What does “No repeats” do?
It guarantees every generated number is different. The count must fit inside the range — for example you cannot ask for 10 unique numbers between 1 and 5.
Can the minimum be larger than the maximum?
No — the calculator will show an error. Swap the two values so the minimum is the smaller number.
Can I generate negative numbers?
Yes. Enter a negative minimum, for example −50 to 50, and the results will include negative numbers. Use it as a random number generator free — no signup, nothing to install.
