PDF Reader adalah

First, an essential note: a PDF reader is a different kind of software than a PDF editor. It is a distinction that is easy to overlook, but it can have a significant impact on how successful you or your staff are when the time comes to work with PDF files. To put it another way, all PDF editors are readers, but not all PDF readers are editors.

In reader software, users typically can only open the PDF file and read its content. They may be able to fill in form fields and save the PDF for printing, but they cannot change or modify any of the information in the document. For that, you need a PDF editor, which has the tools necessary to manipulate the contents of the file.
