One day while whilst watermarking in a series of PDF files, this error message appeared and now it is permanent. It has ceased my working as I need to add watermark in multiple files. Is there any expert who can assist how to overcome this issue?”

PDF is the most popular file format when it comes to sharing the documents between people or different corporations, even if we discuss official documentation. A PDF is also very customizable that we can allow other users to write on it, sign it, or just the opposite, that they can just see it without any option to modify it. In order to make it even more personal and easily identifiable, we can watermark it. Basically, it is done to secure the copyright information.
