Protecting Documents
PDF stands for Portable Document Format. It is a file format developed by Adobe Systems that allows documents to be presented in a manner independent of application software, hardware, or operating systems. Editable formats (like .odt and .docx) allow anyone to make changes. To prevent editing, documents should be saved in a non-editable format.
