JavaScript is switched off or not working — that's okay! InputOutput works fine without it.

Random number generator

Use this tool to generate any amount of truly random numbers — you can select the range, number of digits, decimal places, and if the numbers are unique or not.


        How is this truly random?

        This tool generates cyrptographically secure random numbers using randomness from within your device.

        This is done in the browser using the web cryptography API. (If your browser doesn't support this, a warning message will display above the tool)

        If you have JavaScript turned off cryptographically secure random numbers will be generated on a server for you.
