Frequently asked questions

Can the watermark be removed?

The watermark is rendered as a PDF content layer. While it can technically be removed with advanced PDF editors, it provides a clear visible stamp suitable for drafts and internal documents.

Is the watermark added to every page?

Yes — the watermark is applied uniformly to all pages in the document.

What font and size does the watermark use?

The watermark uses Helvetica at a size that scales to the page. It is positioned diagonally at the center of each page.
