PDF files are becoming increasingly common in our daily work and lives, especially when dealing with formal documents. Adding watermarks to PDFs is a very effective way to protect document content, indicate document status, or make documents look more professional. Whether you want to mark something as “confidential,” add your company’s logo, or simply prevent others from sharing it indiscriminately, a watermark clearly conveys the document’s ownership and purpose.
