How to use the random number generator

  1. Set the range and how many numbers you need.
  2. Tick “No repeats” for lottery-style draws and “Sort” to order them; or click a preset.
  3. Click Generate and copy the result.

Numbers come from your browser’s cryptographically secure random generator (Web Crypto) with rejection sampling, so every number in the range is exactly equally likely — fair enough for giveaways, raffles, classroom picks and games. Decimal mode gives random real numbers with up to 6 decimal places.
