About the random number generator
Updated June 2026 · 100% client-side — your data never leaves your browser.
Generate random numbers within any range you choose. Set a minimum and maximum, decide how many numbers to draw, and optionally allow or forbid duplicates — making it handy for raffles and giveaways, random sampling, picking lottery-style numbers, choosing a winner, or seeding test data.
Numbers come from the browser's built-in random generator, which is well-suited to games, draws and everyday sampling (though not to generating cryptographic keys). Everything happens on your device, so the draw is private and works without a connection.
