Random Number Generator
Unbiased random number picks using the browser's Web Crypto API.
How the random number generator works
The generator picks an integer within the given range using the browser's cryptographically secure Web Crypto API. The “No repeats” option guarantees that no number is repeated when drawing several values.
Number = secure random integer between min and max
The tool is suited for lotteries, prize draws, queue drawings, or any situation that needs an unpredictable pick from a limited set of numbers. It does not replace a certified generator for official cash draws.

FAQ about the random number generator
How does the generator produce random numbers?
The generator uses the browser's cryptographically secure Web Crypto API, so every number in the range has an equal chance of being picked. It is suitable for giveaways, games, and learning exercises, but is not a certified generator for official cash lotteries.
What does “No repeats” mean?
When enabled and you request several numbers at once, each one will be unique — no value will appear twice in the result.
Can I use this generator for an official lottery?
For entertainment and internal draws — yes. Official lotteries with cash prizes typically require certified random number generators with independent audits.
