מחולל מספרים אקראיים

A random number generator that returns whole numbers in any range you set, optionally with no duplicates and optionally sorted, using the browser's secure randomness so the results are genuinely unpredictable.

Everything runs locally with nothing sent to a server, and each run produces a fresh set, since there is no fixed seed to reproduce.

You choose the minimum and maximum and how many numbers you want. The output can allow repeats, or be made unique, in which case the count is capped at the size of the range since you cannot draw more distinct numbers than exist in it.

The randomness comes from crypto.getRandomValues, the browser's cryptographically secure generator, rather than a simple pseudo-random function, so the numbers are not predictable from one another.

That makes it well suited to casual draws and decisions: picking a raffle or giveaway winner, choosing a random participant, rolling for a game, sampling rows for a spot check, or just breaking a tie.

For official lotteries and gambling, certified hardware random generators are legally required; this tool is for everyday, informal randomness rather than regulated draws.
