How It Works

What is a Random Number Generator?

A Random Number Generator is a tool that creates unpredictable numbers within a range you define. Perfect for games, raffles, random decisions, statistical sampling, and creating test data for software development.

Cryptographically Secure Algorithm

Our tool uses the browser's Web Crypto API to generate truly random numbers. Unlike standard Math.random(), this method is secure for applications requiring real unpredictability, like key generation and lotteries.

Frequently Asked Questions (FAQ)

Are the numbers truly random?

Yes. We use the browser's Web Crypto API, which provides cryptographically secure randomness. It's suitable for security applications and lotteries.

Can I generate decimal numbers?

Yes. You can choose between integers or decimals, with configurable precision from 2 to 10 decimal places.

How to avoid repeated numbers?

Enable the 'Unique Numbers' option to ensure each number is different. The maximum pool is limited to the range size.

What's the maximum numbers per generation?

You can generate up to 100 numbers at once. For small ranges, make sure the requested number doesn't exceed the range size when using unique numbers.

This tool is for legitimate purposes. Use in fraudulent activities is illegal.
