Is the randomness truly random?

This tool uses the Web Crypto API (crypto.getRandomValues) for cryptographically secure randomness, far stronger than Math.random(). Suitable for raffles and scenarios requiring true randomness.

How to generate unique random numbers?

Check the 'No repeats' option. Note: the count cannot exceed the range size. For example, you can generate at most 10 unique integers between 1 and 10.

Can I generate decimal numbers?

Yes. Switch the type to 'Decimal' and set the number of decimal places (1-10). Default is 2 decimal places.
