Calculation Logic

  • Picking: Generate uniform random indices using Web Crypto.
  • Shuffling: Apply Fisherโ€“Yates swaps from end to start; randomness comes from crypto.getRandomValues().
  • Uniqueness: In no-duplicate mode, we draw from a shrinking pool to ensure unique winners.

FAQ

Is this random picker truly fair?

Yes. We use the browserโ€™s crypto.getRandomValues() API instead of Math.random() for cryptographically secure randomness.

Can I pick multiple winners without duplicates?

Yes. Disable โ€œAllow Duplicatesโ€ and the tool guarantees each winner is unique.

Is my data safe (local/privacy)?

Yes. Lists and results are processed locally with no uploads or server storage.

Is it free? Can it remember my list?

Itโ€™s free. Optional local storage can keep your list after refresh (you can clear it anytime).

Why not use Math.random()?

Math.random() isnโ€™t designed for security or strong fairness. Web Crypto provides higher-quality, less predictable randomness.
