Watermark PDF questions
Short answers, then the practical details.
Can I watermark only some pages?
Yes. Enter the first and last page numbers for an inclusive range. Enter the same number twice to stamp a single page. The default range covers the whole document.
Can I use a logo or add a watermark behind the text?
Yes. Choose Image for a PNG or JPEG up to 10 MB. Select Under content to place the stamp behind it. An opaque scan or background may hide an underlay, so use the preview to check.
Will a watermark prevent editing or copying?
A watermark labels the document and does not restrict copying or editing. Zipora adds PDF content while preserving existing selectable text. Editing a digitally signed PDF can invalidate its signature.
