ABOUT THE TOOL
A simple random number generator
This free random number generator creates pseudo-random integers within a range you choose. It runs directly in your browser, so there is no account, download, or server request needed to generate a number.
Use it for games, classroom activities, giveaways, testing, choosing a random value, or any situation where you need a quick number.
UNDERSTANDING THE OPTIONS
What are unique numbers?
When you enable "Unique numbers only", RandomTools makes sure that the same number does not appear more than once in your results.
For example, if you generate five unique numbers between 1 and 20, every number in the result will be different. If the option is disabled, a number may appear more than once.
COMMON USES
What can you use it for?

IMPORTANT
How random are the results?
RandomTools uses standard browser-based pseudo-random number generation to produce its results. The generated numbers are intended for general-purpose randomization.
