What is a Random Number Generator?
A random number generator (RNG) produces numbers that cannot be reasonably predicted. This tool lets you generate numbers within a specified range, which is useful for lottery draws, giveaways, sampling, testing, games, and simulations.
By default, numbers are generated using your browser's standard random source, which is fast and good enough for most uses. Enable the Secure random option to use a cryptographically secure source (based on crypto.getRandomValues) suitable for passwords, tokens, and security-sensitive applications.
