About the Random Number Generator

The Random Number Generator draws numbers from a range using the browser's cryptographic randomness — single draws, bulk lists, or unique picks without repetition (lottery style). Results can be sorted ascending or descending and joined by newline, comma or space.

Yes — crypto.getRandomValues provides unbiased, unpredictable output, unlike Math.random.

All tools are free. Results are informational — no guarantee of accuracy.
