Frequently Asked Questions
How random are the numbers?
The tool uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers suitable for security-sensitive applications.
Can I generate unique random numbers?
Yes. Enable the Unique toggle to ensure all generated numbers are different. Note that the range must be large enough to accommodate the requested count of unique values.
What decimal precision is supported?
You can set decimal places from 0 (integers) to 10 for high-precision decimal numbers.
Is my data uploaded to a server?
No. All number generation happens in your browser using the Web Crypto API. Nothing is sent to any server.
