Watermark Examples

Use Case: Protecting Business Documents

Add your company logo to contracts or reports to reinforce your brand and prevent unauthorized use. Combining a semi-transparent logo with a text watermark like "Draft" ensures your PDFs are secure and professional.

Tip: Optimize Watermark Appearance

Use a high-resolution logo for clarity and adjust transparency (e.g., 30%) to balance visibility and readability. Test different positions to find the best placement for your PDFs.
