Frequently Asked Questions
Can I generate negative numbers?
Yes, both the minimum and maximum fields accept negative values. The tool works with any integer range.
How many numbers can I generate at once?
The tool handles thousands of numbers comfortably. Large batches are generated in milliseconds.
What happens if Min is larger than Max?
The tool detects the swap and either warns you or automatically reorders the boundaries so the range is always valid.
How does “unique only” mode work?
With unique mode enabled, the tool guarantees no number appears twice. Note that the quantity cannot exceed the size of the range in this mode.
How random are the generated numbers?
The tool uses JavaScript’s Math.random() (or crypto.getRandomValues() where available) to produce a uniform random distribution across your range.
Are the numbers suitable for cryptography?
For casual and testing use they are perfectly fine. For security-critical cryptographic work, prefer a dedicated CSPRNG-based tool.
Is this random number generator free?
Yes, 100% free with unlimited generation and no sign-up.
Does it work offline?
Yes, once the page loads all generation happens locally in your browser without any server calls.
Is my data secure?
There is no input data to secure beyond the range you enter, and those values are never transmitted anywhere.
