FAQ

Is this the same as RANDOM.ORG true random?

No. This page uses your browser’s Web Crypto CSPRNG (crypto.getRandomValues), a strong PRNG suitable for games, picks, and development — not atmospheric noise.

Can I generate unique numbers only?

Yes. Uncheck “Allow duplicates” and the tool samples without replacement within the range.
