Adding watermark to PDF is the process of inserting an image or text over the existing content of a Portable Document Format (PDF) file. This technique provides an extra layer of protection and authenticity to sensitive documents. In the legal and business world, adding a watermark can deter unauthorized copying and distribution.
Watermarking PDFs offers several benefits. It helps preserve intellectual property, prevents document tampering, and enhances brand recognition. Historically, watermarks originated from medieval papermaking techniques, where manufacturers embedded unique designs into the paper during production. Today, digital watermarks provide a more secure and versatile approach.
