Random numbers done properly
Secure randomness
Numbers come from the browser's cryptographic random generator, the same source used for passwords and keys.

Many generators favour some numbers when the range does not divide evenly. This one throws away the uneven draws, so every value has exactly the same chance.
No repeats
Draw unique numbers for lotteries, raffles or random orders. The tool tells you when the range is too small.
