A watermark is not a copyright registration. It is a social signal: this copy is a proof. Watermark PDF repeats your text — CONFIDENTIAL, DRAFT, a studio name — at an opacity that keeps the document readable.
Diagonal is hardest to crop away in a screenshot. Pair with Protect PDF if the recipient should need a password as well.
We do not add a second “made with” line. The only mark on the page is the one you typed.
