Random Number Generator
Generate single or multiple random numbers in any range — integers, decimals, and unique lists.
How to Generate Random Numbers Online
Set your minimum and maximum values, choose how many numbers to generate, and click Generate. The tool uses the browser's Web Crypto API for cryptographically strong randomness — not the weaker Math.random() function used by most simple generators. Enable "No duplicates" to get a unique list of numbers within your range, useful for lottery picks, random sampling, or drawing winners.
Common Use Cases
Random number generators are used for lottery number picks, random sampling in research, game mechanics, password or PIN generation, selecting random winners from a list, dice roll simulations, and testing software with random inputs.
Frequently Asked Questions
Set minimum to 1 and maximum to 10, then click Generate. The tool uses cryptographic randomness for a fair result.
Yes. This tool uses the Web Crypto API's getRandomValues(), the same source used for security applications — far more random than Math.random().
