Random Number Generator
Pick random numbers between any range - integers or decimals, duplicates or unique.
How to use

- Choose how many numbers and whether you want integers or decimals.
- Uncheck "Allow duplicates" for unique numbers (e.g. lottery-style draws).
- Click Generate, then copy individual results or the whole batch.
Frequently asked questions
How do I pick a random number between 1 and 10?
Set min to 1, max to 10, choose integers, and click Generate. Each result is drawn independently using the browser's cryptographic random source.
Can I generate numbers without duplicates?
Yes. Uncheck "Allow duplicates" and the generator produces unique numbers within the range. If the requested count exceeds the range size, it is automatically capped.
Is this truly random?
Numbers come from the Web Crypto API's cryptographically secure generator - the same quality used for security keys, far stronger than typical Math.random-based tools.
