About this tool

A watermark shows that a document is a draft, confidential, or a copy provided for a specific purpose — for example “Copy for visa application only”. Type your text, then choose its colour, opacity and position: diagonal across the page, horizontal in the centre, or along the top or bottom edge.

The text size adjusts automatically to the page, and any language works, including Arabic, because the watermark is rendered as a transparent image layer on top of each page.

Questions about Watermark PDF

Can the watermark be removed later?

It is part of each page's content, so it is not trivial to remove. Keep your original if you need a clean version.

Will it hide my text?

At 20–30% opacity the text underneath remains readable.

Can I use Arabic text?

Yes. Arabic and any other script are supported.
