How to generate random numbers

  1. Enter the lowest and highest value and how many numbers you need.
  2. Tick No repeats for draws where each number may appear only once, like a lottery.
  3. Press Generate. Copy puts the result on your clipboard, separated by commas.

The presets fill in common draws with one tap.

Fair and truly random

Every result comes from crypto.getRandomValues, the cryptographic random generator built into your browser. Each entry has exactly the same chance, and nothing is decided in advance or on a server.

Both limits are included: 1 to 6 can return 1 and 6. Without repeats you can draw at most as many numbers as the range contains.
