About this tool
Random Number Generator produces one or more random numbers within a range you set, using your browser's cryptographically secure random source — the same quality of randomness used for security-sensitive tasks, not a predictable pseudo-random sequence. Use it for picking a raffle winner, rolling dice, deciding between options, generating sample data, or any situation calling for a genuinely unbiased random pick. Turn on "No duplicates" to draw unique numbers, similar to a lottery draw, or "Whole numbers only" off to get decimal values.
