Generate one or many random numbers between any range. Fast, free, and unbiased.
A random number generator (RNG) is a tool that produces numbers with no predictable pattern. Our tool lets you set a minimum and maximum range, choose how many numbers you want, and decide whether duplicates are allowed.
True randomness is surprisingly hard to achieve. This tool uses your browser's built-in random function to ensure every number in your range has an equal probability of appearing — no patterns, no bias.
Think of it like rolling a dice — except you get to decide how many sides the dice has. Need a number between 1 and 10? Set the range. Need a lottery number between 1 and 49? Easy. Need 6 unique numbers for a raffle? Check "no duplicates" and generate 6 at once.
Common uses include picking lottery numbers, creating random passcodes, running classroom activities, making decisions when you can't choose, and generating test data for developers.
