Frequently asked questions

How random are the numbers?

Numbers come from the browser's cryptographically strong random source rather than a simple seeded formula, which makes the results suitable for giveaways and draws.

Can I stop the same number repeating?

Yes. Turn on unique results and every number in a draw is picked only once — exactly what you need for raffle winners or team assignments.

Is there a limit on the range?

You can set any sensible whole-number minimum and maximum, including negative values, and generate multiple numbers in a single draw.

Is Random Number Generator free to use?

Yes. Random Number Generator on Klipza is completely free with no account, no subscription and no watermark on your files, and there is no daily usage limit.

Are my files safe when using Random Number Generator?

Processing happens locally in your browser wherever technically possible, so your files are not uploaded to a server, stored or shared with third parties.

Does Random Number Generator work on mobile phones?

Yes. It is fully responsive and runs in any modern browser on Android, iPhone, iPad, Windows and macOS — nothing to install.
