How It Works

Our random number generator uses the Web Crypto API's <code class="bg-gray-100 px-2 py-1 rounded">crypto.getRandomValues()</code> method, which provides cryptographically strong random values. This ensures that the generated numbers are truly random and suitable for security-sensitive applications.

The generator supports both inclusive and exclusive ranges, handles negative numbers, and provides options to prevent duplicates when generating multiple numbers. All calculations are performed client-side for maximum privacy and speed.

Privacy Notice: All number generation happens in your browser. No data is sent to our servers, ensuring complete privacy and security of your generated numbers.
