Let me illustrate. Start your copy of Word 2013 and select to open a PDF document.
Word is kind enough to tell you that it will convert your PDF document to an editable Word document. Depending on the size of the PDF document, this might take several minutes. If the PDF document contains many images, they might appear a bit mixed up. But the main thing is that the once read only PDF document is now editable.
The solution to protect it, is a simple one. When you save a document as a PDF in Word, click on the Options button.
The Save options for a PDF document now allows you to protect the document with a password.
You documents are now safe from being opened and modified by unauthorised people. You can store your information on secure drives or storage spaces, but if the document itself isn’t secured it might be the weak link in your security measures.
