Random Number Generator

What Is a Random Number Generator?

A random number generator is a tool that produces numbers selected randomly from a defined range. This free Random Number Generator lets you specify the lowest and highest possible values and then creates one or more random integers within that range.

Random numbers can be useful for games, raffles, drawings, testing, demonstrations, classroom activities, simulations and many other everyday tasks. Because the generator runs directly in your browser, you can create results without installing software or creating an account.

Why Use the Random Number Generator?

The tool provides a simple way to generate random integers while giving you control over the range, number of results, duplicate handling and result order.

How to Use the Random Number Generator

Generating random numbers takes only a few seconds. Define the range and output options, then generate your results.

1. Enter the minimum number — Enter the lowest integer that can be generated.
2. Enter the maximum number — Enter the highest integer that can be generated.
3. Choose the number of results — Select how many random numbers you want, from 1 to 100.
4. Generate the numbers — Click Generate Numbers. You can optionally enable unique numbers or select a sorting method before generating.

Generate Random Numbers Online

This free random number generator creates integer values between a minimum and maximum number that you specify. Both endpoints are included, so if you enter 1 as the minimum and 10 as the maximum, every integer from 1 through 10 can be selected.

You can generate a single random number or produce up to 100 results at once. The unique numbers option is useful when duplicate results would not be appropriate, such as when selecting different numbers for participants in a simple drawing or choosing distinct values for a test dataset.

Random Number Generator for Any Range

The generator supports positive numbers, zero and negative integers. For example, you can generate a random number between 1 and 50, select a value from 0 to 1,000, or generate integers from -100 to 100. The minimum value must not be greater than the maximum value.

Generate Multiple Random Numbers

When multiple results are required, enter the desired quantity and generate them together. Results can remain in the order in which they were produced or be sorted numerically. If unique numbers are enabled, the requested quantity cannot exceed the number of distinct integers available within the selected range.

Random Number Generator Information

The generator produces whole numbers only. The minimum and maximum values are inclusive, meaning either boundary can be returned as a result. The quantity of results can be set from 1 to 100.

When unique numbers are enabled, every result in the current generation is different. Without this option, the same number may appear more than once because each result is independently selected from the specified range. The tool performs its calculations in your browser and does not require a server-side submission of the values you enter.
