Frequently asked questions
Are the numbers truly random?▾
They come from crypto.getRandomValues, the cryptographically secure random source built into your browser, with rejection sampling so every number in the range is equally likely.
Are Min and Max included?▾
Yes. A range of 1 to 10 can return 1, 10 or anything in between.
How do I generate random numbers without repeats?▾
Tick No duplicates. Each number can then appear only once, which is what you need for raffles, lottery picks or assigning unique IDs.
Can I generate random decimal numbers?▾
Yes. Set Decimals to 1–6 to get numbers such as 3.72 between your Min and Max.
How many numbers can I generate at once?▾
Up to 10,000 per click, all generated locally in your browser.
