How the Random Number Generator Works

The tool uses cryptographically strong browser randomness and unbiased integer selection, then applies your uniqueness and sorting rules.

Generate a Random Number Between 1 and 100

The default minimum of 1 and maximum of 100 matches the classic random number picker. Change either boundary for a custom range.

Generating Multiple Random Numbers

Generate up to 1,000 values, including negative ranges and decimals with one to six places.

Random Numbers Without Duplicates

Turn duplicates off to sample unique values. The generator reports when the range cannot supply the requested quantity.
