Random
Random Number Generator
Generate truly random numbers using cryptographically secure randomness. No patterns, no prediction.
Frequently asked questions
How random are these numbers?
We use crypto.getRandomValues(), a cryptographically secure random number generator. It's the same method browsers use for encryption — far more random than Math.random().
Can I generate negative numbers?
Yes! Just enter a negative number in the Min field. For example, Min: -100, Max: 100 will generate numbers in that full range.
What happens with unique + count larger than range?
If the range is too small for the requested unique count, we generate as many unique numbers as the range allows.
What does 'sort results' do?
When enabled, the generated numbers are sorted from smallest to largest for easier reading. This doesn't affect the randomness of generation itself.
Generate random numbers using cryptographically secure randomness (crypto.getRandomValues). Control the range, count, uniqueness, and sorting to get exactly the set you need.
