How this stays fair and unbiased
This tool uses the Web Crypto API's secure random source rather than a simple pseudo-random function, and applies rejection sampling so every number in your range has an exactly equal chance of being picked — a naive modulo approach can subtly favor lower numbers, especially for ranges that don't divide evenly.
Yes — check "No duplicates" and each number in your result will be unique. The count you ask for can't exceed the size of your range in that mode, since there wouldn't be enough distinct numbers.
For informal use — picking a winner among friends, a small raffle, sampling — yes. For anything with real legal or financial stakes, use a purpose-built, auditable random-drawing service instead.
