Frequently asked questions
How do I set the minimum and maximum range?
Type your lowest allowed value into the minimum field and your highest into the maximum field, then click generate. The random number generator returns a whole number that is greater than or equal to your minimum and less than or equal to your maximum.
Are the numbers truly random?
The tool uses your browser’s built-in pseudo-random number generator, which is more than random enough for giveaways, games, and everyday picks. For cryptographic or security-critical use, a dedicated hardware random source is recommended instead.
Can I generate more than one number at a time?
Yes. Just generate again for each new pick, or use the multiple-numbers option if shown. Each result is independent, so the same number can appear twice unless you specifically need unique draws.
Is the random number generator free and private?
It is completely free with no account required. Everything is calculated locally in your browser, so your ranges and results are never uploaded or stored on any server.
