A watermark is a powerful layer of security and branding. By overlaying text like "DRAFT", "CONFIDENTIAL", or your organization's name across every page, you establish clear ownership. PDFNest makes it easy to add professional-grade watermarks without expensive software.

Our tool overlays text at a precise 45-degree angle with optimized opacity, ensuring your original content remains readable while the watermark acts as a permanent badge of identity — perfect for legal professionals, creative agencies, and researchers.
