What the Random Number Generator does
This free tool produces random numbers inside any range you choose. Set a minimum and maximum, pick how many numbers you want, and it returns the list instantly. It is handy for raffles and giveaways, picking a lottery line, choosing a winner from a list, assigning lab samples, seeding test data, or settling a “who goes first” argument. Teachers use it to draw a student at random; developers grab a batch of values for QA.
How to use it
- Enter the Minimum number (defaults to 1).
- Enter the Maximum number (defaults to 100). The max must be equal to or higher than the min.
- In How many, type how many numbers you want, anywhere from 1 up to 1000.
- Tick Unique only if no number should repeat. With this on, your count cannot be larger than the size of the range.
- Press Generate. Each number appears on its own line, ready to copy with one click.
Why generate numbers here
Everything happens in your browser, so there is no waiting on a server and nothing about your draw is sent anywhere. It is free, needs no account, and works the same on a phone, tablet or laptop. Results show one per line, which makes them easy to paste straight into a spreadsheet, a document, or your code.
A quick note on fairness: the numbers come from your browser’s built-in randomness, which is great for games, draws, sampling and test data. For regulated gambling or cryptographic keys, use a purpose-built system instead.
Tips
Turn on Unique only when you are drawing names or seats and need each result to be different. Leave it off when repeats are fine, such as simulating dice rolls or coin-style outcomes. To draw a single value (one winner, one number), just set How many to 1.
Frequently asked questions
- How do I generate random numbers without repeats?
- Tick the Unique only checkbox before you press Generate. Every number in the list will then be different. Keep in mind your count cannot be larger than the range itself, so a 1 to 10 range can give at most 10 unique numbers.
- How many random numbers can I generate at once?
- You can request between 1 and 1000 numbers in a single generate. Each one is printed on its own line so you can copy and paste the whole batch into a spreadsheet or document.
- Can I pick the range for the random numbers?
- Yes. Set any Minimum and Maximum you like, for example 1 to 49 for a lottery line or 100 to 999 for three-digit IDs. The maximum just has to be equal to or greater than the minimum.
- Are these numbers truly random and private?
- They come from your browser's built-in random function and are generated entirely on your device, so nothing is uploaded. That makes them ideal for draws, games, sampling and test data, though not for cryptographic keys or regulated gambling.
