What is Watermark PDF?
A watermark such as CONFIDENTIAL, DRAFT or your company logo marks a document's status or ownership. Here you see the result before you save: drag the watermark where you want it on the page preview and adjust its size, angle, opacity and colour.
Use a text watermark with a choice of fonts, or upload an image or logo. Tile it across the whole page for a repeating pattern. Everything runs in your browser.

Good to know: The watermark is drawn on top of the page content. A low opacity keeps the text underneath readable.

Use it for draft contracts, internal documents, sample pages and branded handouts. A light opacity around 20 to 35 percent keeps the page readable.
Tip: to also number pages, use Add Page Numbers afterwards.
