Random Number Generator
Set a min and max, choose how many numbers and pick integers, decimals or a unique sequence. Numbers are crypto-secure and generated in your browser.
Numbers are generated in your browser using crypto.getRandomValues. Nothing is sent to a server.
How to use this random number generator
- Pick a mode — integers, decimals or a unique sequence.
- Set the minimum, maximum and how many numbers to generate.
- Choose sort order and output format (list, CSV, lines).
- Click Generate, then Copy or Download the result.
Frequently asked questions
Are the numbers truly random?
They are generated with your browser's cryptographically secure random source (crypto.getRandomValues), suitable for raffles, draws and sampling.
Can I get unique numbers without duplicates?
Yes. Enable 'No duplicates' for integers or use the 'Unique sequence' mode to draw without repeats.
What is the maximum count?
You can generate up to 10,000 numbers per run.
Why does my random output sometimes look 'clumpy' — long runs of similar numbers?
Genuinely random sequences are clumpy. Three repeats in a row, or five low numbers before a high one, is exactly what randomness produces — humans expect alternation and read it as 'broken' when they don't see it. Run a larger sample and the distribution flattens out.
