Frequently Asked Questions
Does adding a watermark distort book typography or illustrations?
No. The watermark is placed as an independent graphic state layer, leaving your typography, book layouts, and chapter illustrations crisp.
Is my unpublished manuscript protected from copyright theft?
Yes. Because PDFZento runs 100% on-device without cloud servers, your unpublished manuscript and creative writing are never exposed online.
Can I place the watermark behind the text instead of in front?
Yes. You can configure layer ordering to place the watermark beneath text so high-contrast reading remains completely unobstructed.
