Frequently asked questions
Is the randomness cryptographically secure?
No — it uses Math.random(), which is a PRNG suitable for non-security purposes (testing, draws, sampling). For passwords or cryptographic seeds, use the Password Generator (which uses crypto.getRandomValues).
Can min equal max?
Yes — you'll get the same number repeated. If max < min, max is auto-corrected to equal min.
What's the maximum quantity?
10,000 per click. Beyond that, the browser may freeze. For larger sets, generate in batches.
Are duplicates allowed?
Yes — random with replacement. For unique numbers, generate a larger set and dedupe (or use a different tool).
Can I use it for raffles?
For casual draws, yes. For audited/legally-binding draws, use a notarized RNG service.
