Enter a minimum and maximum value, choose how many numbers to generate, and get a set of random integers within your range. You can also control whether duplicates are allowed and how the results are sorted — low to high, high to low, or unsorted.

A random integer generator produces whole numbers chosen at random within a specified range. Each number is selected independently, similar to rolling a die or drawing a ticket from a hat. This tool uses JavaScript's built-in Math.random() function, which is a pseudo-random number generator (PRNG).
Pseudo-random numbers are produced by a mathematical algorithm and are deterministic — given the same starting conditions, the same sequence can be reproduced. True random numbers are derived from physical phenomena like atmospheric noise and are not reproducible. For most everyday uses such as games, simulations, and sampling, pseudo-random numbers work perfectly well.
Yes, by default duplicates are allowed, meaning the same integer can be generated multiple times — just like repeated dice rolls. If you need unique numbers only, set the 'Allow Duplicates' option to 'No'. Note that if you request more unique numbers than the range contains, the tool will cap the output at the range size.
You can generate up to 100 random integers at a time with this tool. If you need a large batch of unique numbers, make sure your min-to-max range is wide enough to accommodate your requested count.
Simply set the Minimum Value to 1 and the Maximum Value to 10, choose how many numbers you want, and click Generate. Each result will be a whole number from 1 to 10 inclusive.
Yes. You can enter any negative number as the minimum value — for example, Min: -50 and Max: 50 — and the tool will generate integers across that full range including negatives, zero, and positives.
The numbers are pseudo-random, generated using JavaScript's Math.random(). While not cryptographically secure or derived from physical noise, they are statistically uniform and unbiased for the vast majority of everyday use cases including lotteries, games, sampling, and educational purposes.
Sorting arranges your generated integers in ascending (low to high) or descending (high to low) order after they are randomly selected. The randomness of selection is not affected — sorting only changes how the results are displayed.
