Why do I need to Add Watermarks to PDF Files Using Node.js Cloud API

Adding watermarks to a PDF enhances security, branding, and providing context. Watermarks help discourage unauthorized sharing by clearly marking a document as “Confidential”. They can also convey the status of the document, such as “Draft”, “Approved”, or “For Review”, helping readers understand the context or stage of the document. Also, watermarks can indicate copyright or ownership, reducing the likelihood of intellectual property theft and providing a legal standing in case of unauthorized reproduction. For many companies, watermarked documents can add a layer of professionalism and control over how documents are perceived and shared externally.
