Frequently Asked Questions
How random are the generated numbers?
The tool uses the browser's crypto.getRandomValues() function which provides cryptographically secure random numbers, suitable for most non-malicious purposes including raffles and sampling.
Can I generate numbers without duplicates?
Yes, toggle the "unique values" option and the tool will ensure all generated numbers in a batch are distinct, as long as the range is large enough.
