Add a full-screen diagonal watermark to PDF files that covers the entire page, effectively preventing the watermark from being cropped, blocked, or removed with editing tools for better protection. Many users don't know how to add a full-screen watermark to PDFs. Here's a very simple method to batch add diagonal text watermarks to multiple PDFs with one click. It supports custom text content, font, color, transparency, and more, giving your files an electronic anti-counterfeit label.
Why add a full-screen watermark to a PDF?
Ordinary watermarks only occupy a specific spot on the page, such as the four corners or the center. The watermark area is small, unobtrusive, and can easily be cropped or smeared away, offering minimal protection. A full-screen watermark, however, covers the entire page in a diagonal or dense pattern, making it nearly impossible to remove completely.
A full-screen text watermark covers the entire page. Manually erasing every single watermark from a dense grid is not only difficult but also an enormous workload. Additionally, with text watermarks covering the whole page, no matter which part someone captures, the watermark will be included, allowing the file to be identified as watermarked at a glance.
Many people only add ordinary watermarks to PDFs, thinking that a full-screen watermark is very troublesome and complex. That is not the case. The method taught below allows you to easily apply a full-screen text watermark to a PDF. You do not need to manually adjust the number or position of the watermarks. Simply input the watermark text, and it will be automatically arranged, saving time and effort!
