Adding watermarks to PDF files can be a challenging process, especially if you do not have access to professional tools or have limited technical skills. Watermarks are important to protect your documents from unauthorized use and also provide a way to customize your PDFs. The problem is that many existing tools either cost money, have a complex user interface, or require installation, which makes the process cumbersome and time-consuming. Furthermore, not all tools support a variety of file formats, limiting the options for editing PDFs and other documents.
