Add Watermark to PDF — Free

PDF watermarking adds persistent branding or security marks to document pages, protecting intellectual property and establishing document authenticity. Our watermark tool overlays text or images across your PDF pages with precise control over position, opacity, and appearance.

Choose text watermarks with custom content, font, size, color, and rotation angle. Common options include "CONFIDENTIAL," "DRAFT," "COPY," and custom text. Image watermarks apply your logo or graphic with adjustable size, position, and transparency. Watermarks can appear in the foreground (over content) or background (behind content).

Legal firms watermark confidential documents to clearly indicate privileged status. Businesses mark internal documents to prevent unauthorized distribution. Publishers add copyright watermarks to review copies. Educational institutions mark examination papers and coursework. Government agencies apply classification markings to sensitive documents.

Position controls place watermarks in corners, centered, or at custom coordinates. The tiled option repeats watermarks across the entire page for maximum coverage. Page selection allows watermarking all pages, odd pages only, even pages only, or specific page ranges. Preview mode shows exactly how watermarks will appear before processing.
