About random number generator
A random number generator picks numbers within a range you set, for draws, games, sampling and decisions.
Options
- Set the lowest and highest number, both included.
- Choose how many numbers you need.
- Turn off duplicates for a draw where each number can appear only once, such as a lottery-style pick.
Fairness
Numbers come from your browser's random source. This is fine for everyday use, but not a replacement for an official, audited draw.
A worked example
To choose 5 winners from 100 entries, set the range to 1–100, ask for 5 numbers and switch duplicates off. The tool gives five different numbers, and you match them to the entry list.
For fair draws
Publish the rules and the method in advance. For contests with prizes, local laws may require an auditable process, so check them before running one.
