The Random Number Generator is a free online tool that generate cryptographically secure random integers, decimals, gaussian values, dice rolls, and lottery picks — all in your browser.. It runs entirely in your browser with no installation or sign-up needed.

They are cryptographically secure pseudo-random via Web Crypto (crypto.getRandomValues) — the same primitive used for key material, suitable for games, simulations, and most security-sensitive uses.

Small ranges use a partial Fisher-Yates shuffle; larger ranges use a Set-backed rejection loop. The tool validates max-min+1 >= count before generating.

Box-Muller transform: z = sqrt(-2*ln(u)) * cos(2*pi*v), then scaled by your mean and standard deviation.
