About

Pick a random number within a specific range

This tool generates random numbers between your chosen minimum and maximum values. You can generate one number or a list, choose integers or decimals, avoid repeats, sort the results, and copy or download the output.

Security

  • Default mode uses window.crypto.getRandomValues for stronger randomness than Math.random().
  • Unique integer generation uses unbiased selection to avoid modulo bias.
  • Seeded mode is available for reproducible results, but it is not cryptographically secure.

Use cases

  • Giveaways and raffles
  • Games and classroom activities
  • Testing, sampling, and quick decisions
