When you want to make it very clear who owns certain PDF files, you can just place a watermark on them and be done with it.

Star PDF Watermark Ultimate is one of the tools you can turn to for this purpose.

The application comes with a no-frills graphic interface that makes it very simple for novices to find their way around.

You simply need to start by adding the PDF files you want to process, then customize the text or image watermarks to your heart's desire.

As soon as the list of source files is completed, you can start tinkering with the configuration of the watermarks.

When it comes to a text watermark, you need to enter its contents, then select the font type, size and color. The location can be adjusted as well - if you are not pleased with one of the available positions, you can modify the vertical and horizontal offset manually.

You can also tamper with the look of the text stamp, by making it look 3D or applying the gradient (choose the start and end colors).

If you prefer an image watermark, simply browse to the location of the pic you require, then specify its position.

A nifty function of Star PDF Watermark Ultimate is that you can create several watermark layers and overlay them.

This way, you can apply several text stamps onto the same document, and configure them differently.

All in all, Star PDF Watermark Ultimate comes in handy when you want to add image or text stamps to your PDF documents, even if you are not a tech-savvy user. You can even select the pages that should be stamped (all, odd, even or first pages).
