Can the watermark be easily removed by others?

The watermark is rendered directly into the PDF vector layer, making it very difficult to remove without professional editing tools.

Does it change the existing text or images in my document?

No. The watermark is applied as a semi-transparent overlay on top of existing contents without disturbing readability.
