Can I use a transparent PNG?

Yes, PNG transparency is fully supported. Transparent areas will not block the underlying content.

Is the watermark removable?

No. The image is permanently rendered onto the PDF pages and cannot be removed after application.

What is the recommended image size?

200-500 pixels width at 72 DPI works well for most documents. The auto-scale mode sizes it proportionally.
