Free Online Random Number Generator

1. Set the minimum and maximum bounds (both inclusive).
2. Set the count for a batch, or leave at 1 for a single draw.
3. Toggle Allow duplicates off if you want unique picks (sampling without replacement).
4. Click Generate, then Copy to send the result to your clipboard.

Uniform random integers seed raffles, sample customers for a survey, assign A/B test buckets, pick a winner from a list and generate test fixtures. Decimals (rounded to a precision you set) cover Monte Carlo runs and any task where integers are too coarse.

This generator pulls bytes from crypto.getRandomValues, the browser's cryptographically secure random source. Unlike Math.random, the output is unbiased and unpredictable, suitable for security-adjacent uses (raffles where money is on the line, fair lotteries, picking a single winner from a verified list).

Set the minimum and maximum (both inclusive), optionally request a batch with or without duplicates, and copy the result as plain integers, one per line. Toggle the no-duplicates option when you're sampling without replacement (a fair raffle where each ticket can win once).
