Frequently Asked Questions About Watermark PDF
Can I add both text and image watermarks?
Yes. You can stamp custom text (e.g., 'CONFIDENTIAL', 'DRAFT', 'COPY') or upload image logos (PNG, JPG) with transparency support.
Can I adjust watermark transparency and rotation?
Yes. You can customize font size, opacity, rotation angle (e.g. 45° diagonal), color, and alignment across all pages.
Does adding a watermark decrease PDF visual quality?
No. The watermark is rendered as a clean vector or high-resolution image overlay without modifying existing content resolution.
