Random Number Generator
The Random Number Generator produces random integers within a range you set, with an optional constraint to keep every result unique — handy for picking lottery-style numbers, randomly selecting participants, or generating quick test values. It works well for teachers running a classroom drawing, developers needing sample data, or anyone settling a decision with a random pick.
The numbers are generated locally using your browser's random number functions, so no request ever goes to a server — each result exists only on your screen.
How to Use the Random Number Generator
- Open the Random Number Generator tool.
- Set the minimum and maximum values for your range.
- Choose how many numbers to generate and whether they must be unique.
- Click Generate to get your result.
Frequently Asked Questions
Can I generate multiple unique numbers without duplicates, like for a raffle?
Yes, enabling the uniqueness option ensures no number appears twice in a single batch, which is ideal for raffles or drawing names.
How random are the numbers this tool produces?
It uses your browser's standard random number generation, which is suitable for games, drawings, and testing, though not intended for cryptographic or security-critical purposes.
Is any information about my selections sent anywhere?
No, every number is generated locally in your browser and nothing about your range or results is transmitted to a server.
