Where can I find details about watermarking?
Here are the articles about watermarking documents with Document Converter Services. This is where you can find everything you need to apply watermarks to your Word, Excel, PowerPoint, and PDF files.
Why aren’t my watermarks visible?
The most common reason for this is that, by default, watermarks are displayed in the background, behind the document’s content. In most cases, this isn’t a problem, as the content of most documents is largely transparent. However, this isn’t the case for PowerPoint presentations or scanned content. Learn more here.
