Random Number Generator
Generate random numbers within any range you choose: a single number for a quick draw, or a list of unique numbers for raffles and random ordering. Generation relies on your browser’s secure random source with unbiased sampling, and nothing is stored anywhere.
How to use
- Enter the minimum and maximum of the range (both ends are included).
- Set how many numbers you want (up to 100).
- Enable unique numbers if you want a list with no repeats.
- Press Generate, then copy the result with the Copy button if needed.
Frequently asked questions
Are the numbers truly random?
The tool uses crypto.getRandomValues, the browser’s cryptographically secure source, with unbiased sampling, so the distribution is uniform and practically unpredictable.
Is the range inclusive?
Yes. If you pick 1 to 100, any integer between them can appear, including 1 and 100 themselves.
When should I use the unique numbers option?
For raffles, seat assignment and any case where a number must not repeat — as long as the range is wide enough for the requested count, otherwise a warning explains it.
What is the maximum count per generation?
Up to 100 numbers at a time. Long lists are shown as a tidy grid of cells to make reading and copying easier.
