Free Random Number Generator — Any Range
Updated September 2026
Generate random numbers between any range with one click. Set min, max, and how many to generate, exclude duplicates, and sort results — free online tool.
Verified Capabilities
Generate whole numbers between any minimum and maximum you set.
Optionally exclude repeats within a batch and sort the results ascending.
Numbers are produced instantly in your browser with no page reload.
Uses Math.random(), not a cryptographically secure generator — and count is capped at 20 per generation with no decimal-number mode.
A random number generator picks whole numbers with no predictable pattern — every number in the range has an equal chance of being selected. This tool uses JavaScript's Math.random(), which is fast and statistically fine for games, raffles, classroom activities, and decision-making, though not a cryptographically secure source.
Common uses for random numbers
- Raffles and giveaways: number each entry and generate a random winner
- Games and dice: simulate dice rolls or generate random outcomes
- Statistics and sampling: pick random items from a list for unbiased selection
- Decision-making: choose between options by assigning each a number
- Random PINs: generate a number within a specific range
What this tool doesn't do
Count is capped at 20 numbers per generation, there's no decimal-number mode, and results are whole integers only. For a security-sensitive use case, reach for the Password Generator instead, which uses the cryptographically secure crypto.getRandomValues() API.
How the Random Number Generator works
Enter the minimum value in the Min field and the maximum value in the Max field.
Enter how many random numbers you want (1–20) in the Count field.
Check "No duplicates" if each number should appear only once (requires range ≥ count), and/or "Sort results" to order them ascending.
Click Generate to instantly produce your random numbers. Click again for a new set.
Tips & tricks
- There is no decimal mode — the tool always generates whole numbers between your min and max values.
- Count is capped at 20 numbers per generation — for larger batches, generate multiple times.
- Uses Math.random(), not a cryptographically secure API — for passwords or keys, use a specialized tool.
Frequently Asked Questions
Are the random numbers truly random?
Numbers are generated with JavaScript's Math.random(), a fast pseudorandom generator that's more than sufficient for games, raffles, and classroom picks. It is not a cryptographically secure source, so don't use it for security keys or anything where an attacker predicting the output would matter.
Can I generate random numbers without duplicates for a lottery?
Yes. Enable "No duplicates" and set your range. For a 6/49 lottery, set min=1, max=49, count=6, no duplicates. Each draw gives unique numbers within the range.
Can I generate random decimal numbers?
No — there's no decimal mode. The tool always generates whole (integer) numbers between your min and max values.
How many numbers can I generate at once?
The Count field is capped at 20 numbers per generation. For larger batches, generate multiple times and combine the results, or use a spreadsheet formula for bulk generation.
Can I use this to generate a random password?
For a numeric PIN, yes. For a full alphanumeric password with symbols, use the dedicated Password Generator tool, which also uses the cryptographically secure Web Crypto API rather than Math.random().
Is my data safe when using the Random Number Generator?
Completely safe. The Random Number Generator processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
Are the results from the Random Number Generator truly random?
Yes. The Random Number Generator uses your browser's standard random number generator (JavaScript's Math.random()), which is suitable for games, decisions, and everyday randomness. It is not a cryptographically secure generator — for security-sensitive use cases like generating passwords or cryptographic keys, use a tool built specifically for that purpose.
Can I customise what the Random Number Generator generates?
Yes. Where customisation options are available, you can add your own items, set numeric ranges, or adjust parameters before generating. Default settings are designed for the most common use case so you can get an instant result without any configuration.
