How to generate random numbers
- Enter the minimum and maximum — the lowest and highest values you want (negative numbers are fine).
- Set how many numbers to generate, from 1 up to 1,000.
- Optionally tick Unique (no repeats) so every number is different, or Sort results to list them in ascending order.
- Click Generate. You will get one number per line, plus a single highlighted lucky number.
- Hit Copy to grab the whole list and paste it wherever you need it.
How the randomness works
Most casual random tools rely on Math.random(), which is fast but not designed to be fair or unpredictable. This generator instead uses your browser native crypto.getRandomValues(), the same cryptographically-secure source used for security-sensitive work. To avoid the subtle modulo bias that creeps in when you fold a 32-bit value into a smaller range, it uses rejection sampling: it discards the few values that would skew the distribution, so every number between your minimum and maximum is equally likely.
When you ask for unique numbers, the tool shuffles the available values with a Fisher–Yates style draw and takes the first few, guaranteeing no repeats. Before it does, it checks that your range is actually wide enough — asking for 20 unique numbers between 1 and 10 is impossible, so the tool tells you instead of looping forever or silently repeating.
What can you use it for?
A random number generator is handy for far more than dice rolls. Use it to pick a winner in a giveaway, choose lottery-style numbers, assign people to teams or groups, sample rows from a spreadsheet, seed a game or simulation, generate test data, settle a friendly decision, or pick a random page, question or prize. Thesort option is useful when you need an ordered draw (like lottery balls), and unique is perfect for raffles where the same ticket should not win twice.
Is it private?
Yes — completely. Every number is generated on your own device using the browser secure random source. Nothing is sent to a server, nothing is logged, and nothing is stored. You can confirm this by opening the tool and then disconnecting from the internet — it keeps working, because there is no server involved at all.
Frequently asked questions
What is the lucky number?
It is the first number drawn in your batch, shown large so you can use the tool as a quick single-pick. It is a genuine random pick — it is chosen before any sorting is applied, so it is not just the smallest value.
Can I use negative numbers or zero?
Yes. The minimum and maximum can be any whole numbers, including negatives and zero, as long as the minimum is not greater than the maximum. If you swap them by mistake, the tool fixes the order for you.
How many numbers can I generate at once?
Up to 1,000 per batch, to keep the output readable and instant. Generate again for another independent, freshly random batch.
Is this good enough for a real prize draw?
The randomness is cryptographically secure and unbiased, which is more than enough for raffles, giveaways and games. For legally regulated lotteries, follow whatever certified process your rules require.
