True Randomness in Your Browser
This tool uses the Web Crypto API's crypto.getRandomValues to generate cryptographically secure random numbers. Unlike Math.random(), which uses a pseudo-random algorithm, this method provides true randomness suitable for security-sensitive applications.
How to Use This Tool
- Set the minimum and maximum values for your range.
- Choose how many numbers to generate (1 to 100).
- Toggle Integer only to restrict output to whole numbers.
- Click Generate to create random numbers.
- Copy individual numbers or all results at once.
Common Use Cases
- Lottery and raffle number generation
- Statistical sampling and simulations
