First things first, what is a watermark? A watermark refers to an image or text that overlays a digital asset such as document, video, and website content. It’s normally monochromatic and transparent to enable people to view the content and at the same time claim your ownership.
Watermarks have long been a great solution to protect content copyright and intellectual property. Securing PDF files with watermarks prevents your content from being stolen or misused. Without watermarks, your valuable digital assets can be vulnerable to content theft and unauthorized use.
Acrobat is probably the most popular software for inserting watermarks into PDF files. For your reference, we’ve published a step-by-step guide on how to watermark PDFs using Acrobat Pro.
There are also many other methods to add a watermark to PDF without Acrobat.
