Random numbers done properly

Secure randomness

Numbers come from the browser's cryptographic random generator, the same source used for passwords and keys.

No hidden bias

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.

Decimals on an exact grid

With 2 decimal places between 0 and 1, all 101 values from 0.00 to 1.00 are equally likely, both ends included.

Big lists, fast

Generate up to 10,000 numbers at once with their sum, average, lowest and highest.

Easy to use elsewhere

Copy one per line, with commas or spaces, or download TXT and CSV files.
