How It Works
The tool uses the browser's built-in randomness to pick a number within your chosen minimum and maximum, with each value in the range equally likely. You can generate a single number or several, and optionally allow or prevent duplicates. Because it is computed locally, results are immediate and nothing is recorded.
When to Use This
Drawing a winner for a giveaway or raffle. Making an unbiased choice between options. Generating sample numbers for a game or test.
Frequently Asked Questions
It uses the browser's random number generator, which is unpredictable and uniform enough for giveaways, games, and everyday decisions.
