Random Number Generator
Generate random numbers instantly within any range. Supports integers, decimals, unique values, and sorting. Free online tool that runs entirely in your browser.
How does this random number generator work?
Set your minimum and maximum values, choose how many numbers you need, and select your options. The tool uses JavaScript's Math.random() to generate truly random numbers within your specified range.
Can I generate only unique numbers without duplicates?
Yes! Simply uncheck the "Allow duplicates" option to ensure all generated numbers are unique. This is perfect for lottery draws, raffles, or any scenario where repetition isn't allowed.
Does this tool support decimal numbers?
Absolutely. Check the "Allow decimals" option to generate random decimal numbers instead of integers. Useful for scientific calculations, statistics, or any application requiring precision.
Is my data safe when using this generator?
Yes, completely safe. All number generation happens locally in your browser using JavaScript. No data is sent to any server, and everything runs offline after the page loads.
Can I sort the generated numbers?
Yes, you can sort the results in ascending order by checking the "Sort results" option. This is helpful when you need organized sequences for analysis or display.
What is the maximum range I can use?
You can use any range from negative to positive numbers. The tool supports the full range of JavaScript numbers, from approximately -9 quadrillion to 9 quadrillion.
How many numbers can I generate at once?
You can generate up to 10,000 numbers in a single batch. For most use cases like lotteries, games, or statistical sampling, this is more than sufficient.
Is this tool free to use?
Yes, this random number generator is completely free with no limitations. No registration, no ads, no hidden fees. Use it as many times as you need.
Can I customize the separator between numbers?
Yes, you can set any separator you prefer - commas, spaces, newlines, or any custom character. This makes it easy to copy and use the numbers in different formats.
Are these numbers truly random?
The numbers are generated using JavaScript's Math.random() function, which uses a pseudorandom number generator. For most applications, this provides sufficient randomness. For cryptographic purposes, consider using specialized cryptographic libraries.
Can I use this for lottery or gambling?
While this tool generates random numbers suitable for casual games and lotteries, please check your local regulations regarding online gambling. The tool is for entertainment and educational purposes.
Does it work on mobile devices?
Yes, the tool is fully responsive and works perfectly on smartphones, tablets, and desktop computers. The interface adapts to your screen size for optimal usability.
How to Use Random Number Generator
Draw random integers or decimals from any range you define, in any quantity — the generation happens entirely in your browser and nothing is sent to a server.
- Type the lower bound of your range into the "Min:" field and the upper bound into the "Max:" field.
- Enter how many values you need in "Count:" — a single pick or a whole batch at once.
- Choose what should sit between the results in "Separator:", such as a comma, space or new line.
- Run the generator and copy the resulting list straight into your notes, game or spreadsheet.
- Generate again as often as you like; every draw is fresh and nothing is logged anywhere.
Set "Min:" 1 and "Max:" 6 with a count of one to roll a virtual six-sided die.
