watermark watermark watermark watermark watermark watermark watermark

Many ways:

  • Use a commercial program (random example)
  • Use whatever tool was used to create the PDF (e.g. Acrobat)
  • Convert the PDF to a more tractable form.

Create a PDF with your watermarks and stamp the original PDF with such a tool: http://pdftools.softonic.de/

You may be interested using Dysprosium free software, I found useful.

  • You can select one page or selected pages or all pages of your document to be watermarked.
  • You can have the same text for those pages or different texts for each page.
  • You are able to watermark, as desired by your question, in many lines using different angles, fonts, and colours
  • Similarly, if you choose to watermark with images.
  • You can watermark one document with pages from another pdf document.
  • Using this software, you can convert an image or a set of images to pdf and then over-lay or under-lay the resulting pdf to your document.
  • You are able to decide for the font, colour, angle, opacity, and scale of watermark.
  • Software does not overwrite the original file, keeping it safe.
  • Software is non-commercial, unlimited, lightweight, and portable and cross-platform as a JAR file.

You can use Adobe Acrobat Pro to add watermark on all or only a few pages of your PDF file.

You'll find this in the menu View / Tools Sets / Default Tools. Then the option to add watermark will be in the "pages" section on your sidebar.

It gives you the option to rotate your text, use any style or size you want, add it in front or behind the text, etc.

You can also use an image if you prefer.

Finally, you can save that watermark as a profile if you need to use it on other projects.

Make sure to keep a duplicate of your original file before testing this!
