How to Add Watermark PDF Files
How to add watermark to PDF online
A watermark is a digital mark (an image or text) embedded in PDFs, photos, illustrations, etc., that indicates authorship or ownership of the marked content. As a standard, it should be semitransparent and barely visible, but visible enough so that the content isn’t usable. If your text falls into the wrong hands, the mark will play a marketing and protective role in keeping your data secure and controlled by you. It helps potential customers identify and contact you as the author while keeping unauthorized users from editing the document.
