- Choose whether repeated values are allowed
- Generate the numbers, then copy or regenerate them
About Random Number Generator
Pick any range and get random whole numbers instantly. Set a minimum and a maximum — 1 to 100, 1 to 10, 1 to 3, or any bounds you like — choose how many numbers you want, and decide whether repeats are allowed. Both ends of the range are inclusive, so your minimum and maximum are always possible outcomes. When you turn off "Allow duplicate numbers," every value comes back unique, which is what you want for raffles, team draws, or picking lottery-style numbers without collisions.
Every number is drawn with crypto.getRandomValues, your browser's built-in cryptographic random source, and rejection sampling strips out the modulo bias that makes cheaper generators lean toward low numbers. That makes the results as fair as a random number generator website like random.org or the one built into Google search — without ads, and with no Python or code required when you just need a number now. You can generate up to 1,000 at once, hit Regenerate for a fresh set, and Copy the whole batch as a comma-separated list to paste anywhere.
The tool is completely free with no sign-up and no usage limits. It runs entirely in your browser, so your ranges and generated numbers never leave your device and nothing is ever uploaded to a server.
Frequently asked questions
- Is the random number generator free to use?
- Yes, it is 100% free with no account, no sign-up, and no usage limits. Generate as many sets of random numbers as you like.
- How do I generate a random number between 1 and 100?
- Set the minimum to 1 and the maximum to 100, choose how many numbers you want, and press Generate. Both ends are inclusive, so every value from 1 through 100 has an equal chance of appearing. Turn off duplicates if you need several different numbers in that range.
- Can I get a random number from 1 to 10?
- Yes. Enter 1 as the minimum and 10 as the maximum, then generate. You'll get a random whole number from 1 to 10 every time, which is handy for quick decisions, games, or dice-style rolls. Change the maximum to widen or narrow the range.
- How do I pick a random number from 1 to 3?
- Set the minimum to 1 and the maximum to 3 and press Generate for a random 1, 2, or 3. It's an easy way to choose between three options or simulate a three-sided draw. The same steps work for any small range like 1-5 or 1-6.
- How is this different from random.org or calculator.net?
- It does the same job — fair random numbers in a range you choose — but everything runs locally in your browser instead of on a remote server, with no ads and nothing uploaded. The randomness comes from your browser's cryptographic generator, so the results are just as unbiased.
- Is this the same as Google's random number generator?
- It serves the same purpose as the random number tool built into Google search: give it a range and it returns a number. The difference is you can generate up to 1,000 at once, block duplicates, and copy the whole set, all without leaving the page or being tracked.
- Do I need Python or any code to generate random numbers?
- No. This tool generates random numbers directly in your browser, so you don't need Python, its random module, or any code. If you're a developer, it's a quick no-code way to grab test values or a random pick without installing or writing anything.
- How random are the numbers?
- The tool uses crypto.getRandomValues, your browser's built-in cryptographic random number generator, with rejection sampling to remove modulo bias. This produces far higher-quality, unbiased randomness than the usual Math.random.
- Can I generate numbers without duplicates?
- Yes. Uncheck 'Allow duplicate numbers' and every generated value will be unique. When duplicates are off, the count you request cannot exceed how many values fit in your range, and the tool will tell you if you ask for too many.
- Are the minimum and maximum included in the results?
- Yes. The range is inclusive on both ends, so both your minimum and maximum values are possible outcomes.
- How many numbers can I generate at once?
- You can generate up to 1,000 numbers in a single batch. Enter your range and count, then use Generate or Regenerate to draw a fresh set, and Copy to grab them all as a comma-separated list.
- Is my data uploaded or stored anywhere?
- No. Everything runs locally in your browser using JavaScript. Your minimum, maximum, count, and the numbers you generate are never sent to a server or saved anywhere.
