What Is a PDF Watermark Adder?
A watermark is a recognizable image or text overlay placed on a document to identify ownership, mark confidentiality, or add branding. This tool lets you add custom watermarks to any PDF — text like "CONFIDENTIAL" or "DRAFT", or an image such as a company logo. You can control position, rotation, opacity, font, and color, and apply the watermark to specific pages or the entire document. All processing happens locally in your browser — nothing is uploaded to any server.

- Configure your watermark — customize text, font, size, color, position, rotation, opacity, and page range.
- Click "Apply Watermark" — the tool processes the PDF and adds the watermark.
- Download the watermarked PDF with the Download button.
