Frequently asked questions
Are the numbers really random?
They come from the Web Crypto API built into your browser, a cryptographically secure generator designed for security keys. Every number in your range is equally likely, and no pattern can be predicted.
How do I pick several numbers without repeats?
Set “How many” and keep “No repeats” ticked. The tool will tell you if you ask for more numbers than exist in the range.
Can I generate decimals or negative numbers?
Yes. Choose 1–3 decimal places, and use a negative minimum such as −50.
Is anything saved or sent anywhere?
No. Numbers are generated on your device and are not stored on our server.
