Frequently Asked Questions
Are the numbers genuinely random?
They come from your browser's cryptographic random source, which is seeded from real system entropy — not a predictable pseudo-random sequence. For a draw or a giveaway that matters, since a predictable generator can be gamed by anyone who works out the seed.
How do I draw without repeats?
Enable no-repeat mode and every number in the range is drawn at most once — which is what you need for raffles, team selection and lottery-style picks where a duplicate would invalidate the draw.
Can I generate many at once?
Yes. Set the count and get the whole set in one go, ready to copy. There is no cap.
Is this fair enough for a public giveaway?
The randomness is sound. What a public draw also needs is transparency — announce the range and the method beforehand, and ideally record the draw. The fairness question is usually about trust rather than the algorithm.
Can I generate decimals rather than whole numbers?
Yes — set the precision and get random values with decimal places, which is what you need for simulations and test data rather than draws.

Tips for better results
- Test the output in its real destination before producing it in bulk.
- Where a size is offered, pick the largest you may need — scaling down keeps quality, scaling up does not.
- The page works offline once loaded, which is useful on an unreliable connection.
Common problems and how to fix them
The output does not work where you pasted it
The destination expects a different format or encoding. Check what it accepts and re-generate accordingly.
The result is too small to use
Increase the size or resolution before generating rather than enlarging the file afterwards.
Nothing happens when you click
A required field is empty, or a browser extension is blocking the script. Try a private window with extensions disabled.
