Frequently Asked Questions
Can I customize the watermark transparency and angle?
Yes. You can adjust opacity from subtle 15% shading to bold stamps, set rotation angles (e.g. 45 degrees diagonal), and select custom text colors.
Does the watermark appear above or below the document text?
The watermark is rendered as an overlay content stream with alpha blending, ensuring it remains visible across both text and background graphics without obscuring reading.
Can someone easily remove a stamped PDF watermark?
The watermark is written directly into each page’s content stream operators, making it impossible to strip without specialized desktop PDF editor software.
