About watermarks
A watermark is a visible label stamped diagonally across every page — useful for marking drafts, flagging confidential documents, or branding a portfolio before it leaves your hands.
Keep the text short (a single word or short phrase works best) and choose an opacity that is legible without overwhelming the content underneath. Thirty percent is a good starting point.
Watermarks add a visual signal but are not a security feature — anyone with a capable PDF editor can remove them. Pair with Protect PDF if you also need password protection.
