Why Add a Watermark to a PDF?

Watermarks serve a clear purpose: they tell the reader something important about the document's status or ownership. A "CONFIDENTIAL" stamp discourages unauthorized sharing. A "DRAFT" mark signals the document is not yet final. Your company name or website URL establishes authorship at a glance.

Adding a watermark is a simple but powerful step when sharing sensitive or unfinished work. After watermarking, you might also want to compress the PDF before sending, or merge it with other documents into one file.
