Details
The random number generator produces random integers in any range you specify. Use it for draws, raffles, test data and game mechanics.
Numbers come from a cryptographically secure generator (crypto.getRandomValues), so results are fair and unbiased. With duplicates disabled, the same number never appears twice.
Everything runs in your browser and nothing is sent anywhere. Generated results are not stored either.
FAQ
Are the numbers biased?
No. A cryptographically secure generator produces fair, unbiased results.
Can I prevent duplicate numbers?
Choose "no duplicates" and the same number never appears twice. Note that you cannot generate more numbers than the range allows.
How many numbers can I generate at once?
Up to 100 at a time.
Are generated numbers saved?
No. Results are shown only in your browser and never saved or sent.
