FAQ
How random are the numbers?
The generator uses the Web Crypto API, a cryptographically secure random source — far stronger than typical pseudo-random generators.
Can I generate unique numbers?
Yes — enable unique mode and the tool will never repeat a value within the generated set.
What if I ask for more unique numbers than the range holds?
You get every value in the range, exactly once. The count is capped at the range size instead of showing an error — e.g. range 1–10 with count 50 returns all 10 numbers.
Can the range include zero or negative numbers?
Yes. Min and max accept any whole numbers, including zero and negatives, as long as max is greater than or equal to min.
Is my data sent to a server?
No. Everything runs locally in your browser and nothing leaves your device.
