How do I add a watermark to a PDF?
Upload your PDF, choose Text or Image watermark, customize the appearance (opacity, rotation, position), and download. The watermark is applied to all or selected pages.
Can I add an image or logo watermark?
Yes. Click Image tab, upload your PNG, JPG, or SVG file. Adjust scale and position, then download.
How do I make the watermark transparent?
Use the Opacity slider (0-100%) to control watermark transparency. 50% is a good starting point for readable but visible watermarks.
Can I watermark only certain pages?
Yes. Under Pages, choose All, First Page, Last Page, or enter a custom range like "1-5, 8, 10-12".
How do I rotate the watermark diagonally?
Use the rotation presets (-45° or 45°) or the custom slider. Diagonal watermarks are harder to remove and look professional.
Can I put the watermark behind the text?
Yes. Choose "Below Content" in the Layer setting to place the watermark behind document text and images.
What image formats work for watermarks?
PNG, JPG, JPEG, WebP, and SVG. PNG with transparency works best for logos.
How do I add a CONFIDENTIAL stamp?
Use the Text presets dropdown and select CONFIDENTIAL. It auto-applies red color, 48px size, and -45° rotation.
