Whether you need to mark a document as "DRAFT", protect intellectual property, or add your company branding, adding a watermark to PDF is the most effective solution. This guide covers watermark types, best practices, and how to do it with PDFMASTER.
Why Use Watermarks?
- Copyright protection -- Photographers, designers, and authors use watermarks to protect their work.
- Document status -- Labels like "DRAFT", "CONFIDENTIAL", or "SAMPLE" clarify the document's purpose.
- Brand identity -- Adding a company logo or name professionalizes corporate documents.
- Deterring unauthorized distribution -- Watermarked documents can be traced back to their source.
Types of Watermarks
- Text watermark -- "CONFIDENTIAL", "DRAFT", "SAMPLE", company name, or custom text. Most common and easiest to apply.
- Image watermark -- Company logo or custom design. Ideal for brand recognition.
- Diagonal watermark -- Text placed diagonally across the page. Visible across the entire document.

Tips for Effective Watermarks
- Balance opacity -- Too dark makes content unreadable; too light is invisible. 15-30% opacity works best.
- Use large font size -- The watermark should span enough of the page to be noticed.
- Place diagonally -- 45-degree angle provides visibility without blocking content.
- Choose gray tones -- Light gray works well with most document backgrounds.
