About the Random Number
A random number generator produces a number within a range you choose. Useful for games, draws, sampling, simulations, or just making an unbiased decision.
This tool generates numbers in your browser. For casual use its randomness is more than enough; for security-sensitive needs (keys, tokens) use a dedicated cryptographic tool instead.
How to use the Random Number
- 1Set the minimum and maximum of your range.
- 2Choose how many numbers to generate (and whether duplicates are allowed).
- 3Generate — the result appears instantly.
- 4Copy the number(s).
Common uses
Giveaways & draws
Pick a winner fairly from a numbered list.
Sampling & testing
Generate random inputs for tests or simulations.
Everyday decisions
Break a tie or make an unbiased choice.
Frequently asked questions
Is this suitable for security (passwords, tokens)?
No. Use a purpose-built cryptographic generator for secrets. This tool is for general-purpose randomness, not security.
Can I get unique (non-repeating) numbers?
Yes — enable the no-duplicates option to draw distinct numbers from your range, like a lottery.
Is the range inclusive?
Yes, both the minimum and maximum you set are possible results.
Is anything sent to a server?
No. Numbers are generated locally in your browser.
