Why add a watermark
SAMPLE, CONFIDENTIAL, DRAFT, a company name or the recipient's name — a watermark tells at a glance what kind of document this is and whether it may be passed on. The tool lays your text over every page of the PDF: you choose the font, size, opacity and angle, see the result in the preview and download the file. A translucent label does not get in the way of reading, yet it stays on every copy and printout.

When you need it
A watermark labels a document wherever its status matters:
- a quote or mock-up goes out for approval;
- a contract or report is marked CONFIDENTIAL;
- a draft must not be mistaken for the final version;
- course materials or a price list circulate with the author's name;
- a copy is issued to a specific recipient — with their name on it.
How to choose the label
For a document status, one word in a large font across the diagonal at 10–20 % opacity is enough — visible, but not in the way. A company or recipient name goes smaller and denser so it cannot be missed. Long text is best shortened: it has to fit on the page in full at the chosen size.
How reliable it is
The watermark becomes part of the page content, like the rest of the text — it survives copying, printing and conversion. But it is not protection: a PDF editor can remove it. To forbid changes, also lock the document with a password using Protect PDF. The page quality does not change when the mark is applied.
