How it works

Generate uniformly distributed random integers within an inclusive range.

Enter a minimum, maximum, and how many numbers you want. The generator draws each number independently from the range using the platform's cryptographically secure RNG.

Formula

Each result x ∈ [min, max] with uniform probability.

min/max
Inclusive bounds (integer)
count
Number of draws (count)

Examples

  • Roll a six-sided die onceMin 1 · max 6 · count 1One random integer from 1 to 6

Frequently asked questions

Is the result truly random?

It uses the platform CSPRNG with rejection sampling, so values are uniform over the range and unpredictable.

Can it pick the same number twice?

Yes — each draw is independent, so repeats are possible (this models sampling with replacement).

How to read the result

Uniform means every integer in the range is equally likely on each draw.

Limitations

Integers only, with no 'unique only' option; draw counts are bounded to 100.

Source: CSPRNG with rejection-sampled uniform indexing.
