About this tool
Need a random winner, a sample set or test data? The generator produces numbers in your chosen range, as integers or decimals, with optional uniqueness.
When to use it: raffles, games, sampling and quick decisions.
Frequently asked questions
Why do I get an error when I ask for too many unique numbers?
If repeats are off, the count cannot exceed the number of integers in your range.
Is it random enough for a raffle?
Yes — it uses your browser’s high-quality random source. For transparency in a public draw, run the pick live on screen.
Can I generate decimal numbers?
Yes — the tool supports decimals within your range, not just whole numbers.
Can I reproduce the same sequence later?
No — there is no seed. Every generation is fresh and independent, which is exactly what you want for fair draws.
How many numbers can I generate at once?
Batches are supported, which is handy for sampling, lottery-style picks and test data.
What are common everyday uses?
Choosing who goes first, picking a winner, sampling rows from a list, or adding chance to classroom games.
