Add Watermark FAQ
Can I customize the watermark opacity, angle, and text color?
Yes. You have full control over font size, opacity transparency, rotation angle (e.g. 45 degrees diagonal), color, and page positioning.
Does watermarking affect the underlying text and graphics?
No. The watermark is stamped as an overlay layer, leaving your original text, vector lines, and embedded images completely unharmed.
Can watermarks be added to specific pages only?
You can choose to stamp every page across the entire document or specify targeted page ranges for copyright and confidentiality notices.
Can someone easily erase the watermark from the PDF?
The watermark is baked into the document's content streams, preventing casual removal in standard PDF reader applications.
