About Random Number Generator

The random number generator creates numbers within specified ranges using either standard pseudo-random (Math.random()) or cryptographically secure (crypto.getRandomValues()) methods. Perfect for lottery numbers, random sampling, gaming, testing, or any scenario requiring unpredictable numbers.

Unique mode ensures no duplicates in the result set, useful for generating lottery tickets, random IDs, or selecting distinct items from numbered lists. Non-unique mode allows duplicates, suitable for dice rolls, statistical sampling, or gaming.

All generation happens in your browser. No numbers are transmitted or logged, important if you're generating sensitive sequences like raffle winners or secure tokens.

Frequently asked questions

Standard uses Math.random(), suitable for games and non-security purposes. Secure uses crypto.getRandomValues(), providing unpredictable randomness for security applications, tokens, or fair drawings.

Yes. Enable "unique numbers" mode. Note: range must be large enough for requested quantity (can't generate 100 unique numbers between 1-10).

Standard mode is pseudo-random (repeatable with same seed, but distribution appears random). Secure mode is cryptographically random (unpredictable, suitable for security). For casual use, both work fine.
