Description:Many times it happens that you need to share documents in a way that none other than the receiver gets the information. Even though a PDF file is non-editable, it does not hide the contents of a file. One can always open the PDF file and access the contents of the same. To deal with this, what you need to and must do is encrypt your PDF file. Adding a password to the document makes it harder for others to redact the information. But how to add a password to a PDF file? This is where the CocoPasswordPDF tool seems helpful.
Technical Details:A PDF stands for portable document format. It can have all types of content starting with the plain text to the graphs, images, clickable links, and fillable forms. While a PDF document is easily shareable or can be transferred to other users, one cannot hide the document traditionally. A password protection tool is what you need to add a password to the PDF file.
