+[TIP]
+Watermarks can be added to exported PDF documents using CSS. Add the watermark styles to the `exportpdf_converter_style` option, targeting `body::after` instead of `#tinymce::after` for proper rendering. For more information see: link:https://exportpdf.converter.tiny.cloud/docs#section/General/CSS[General/CSS].
