Random Number Generator
Generate random numbers within any range. Choose how many numbers you need, whether duplicates are allowed, and whether to restrict results to whole integers.
Generated Numbers
Numbers are generated using the browser's built-in pseudo-random algorithm and are not suitable for cryptographic purposes.
How It Works
This generator uses JavaScript's Math.random() function to produce pseudo-random numbers within your specified range. When "Integers only" is selected, results are rounded to whole numbers. Disabling "Allow duplicates" ensures every generated number is unique — useful for draws, raffles, and sampling.
For large quantities, numbers are displayed as a comma-separated list. For 10 or fewer, each number is shown as a styled card for easy reading.
Frequently Asked Questions
Are the generated numbers truly random?
They are pseudo-random, generated by the browser's built-in algorithm. They are suitable for games, sampling, and everyday use, but not for cryptographic or security-critical applications.
What happens if I request more unique numbers than the range allows?
The generator will alert you that there aren't enough unique values in the given range. Increase the range or decrease the quantity to proceed.
Can I generate decimal numbers?
Yes — simply uncheck the "Integers only" option. The generator will produce numbers with up to 4 decimal places within your specified minimum and maximum range.
