I saved a web page as a pdf.

I would like to add watermark to this existing pdf.

I googled and got an approach that suggest to merge 2 pdf, the original one and the one contains watermark.

this code could used to generate a watermark pdf







although there have to be some additional characters ("ab" in this case).

is it possible use latex to generate a pdf that only contains watermark without any other additional characters?

    Replace ab by ~, for instance.

    I think if your problem is solved, all is fine. What I want to say is that I will be happy to write an answer if you think that will be useful for others, but if you only want to solve the issue then I may not. BTW, you do not need to load graphicx nor xcolor here, and probably want to add \setbeamertemplate{navigation symbols}{}` to remove the navigation symbols on the bottom right.

The following code overlays pages 3 and 4 of the pdfpages manual with a red "DRAFT" watermark:

\newcommand{\watermark}{\tikz[remember picture, overlay] \node [red,opacity=0.3,rotate=45,scale=15.0] at (current page.center) {DRAFT};}

enter image description here

I use the pdfpages package and its macro \includepdf to include an external PDF file:

  • The mandatory argument takes the filename of the external file. In this example, I use the absolute path of the pdfpages manual. You can replace this by the name of your PDF file, and give the relative path instead - i.e. just the filename if the PDF is in the same folder as the LaTeX file.
  • The optional argument pages takes the range of pages of the PDF to be included in the output file.
  • The optional argument pagecommand takes some code to be executed on top of each page. Here, I use tikz to overlay the included pages of the PDF with the word "DRAFT" in red, semi-transparent, rotated, and scaled to a large size. Adjust this as needed.

This is not exactly an answer to the question as stated, but I think it answers the issue you want to achieve if we also consider what you wrote in the other question which we just closed as a duplicate.
