title: .docx, .xlsx, .pdf to .pdf using PHP
body: <p>I have relatively sensitive data in .docx, .xlsx and PDF files that all need to be converted to a single PDF file locally. Sending these files off to phpdocx or Google Docs or anything like this is not an option.</p>
  
  <p>The only other option I am seeing is OpenOffice / LibreOffice but I am not satisfied with how they are converting the documents.</p>
  
  <p>Is there any other alternative anyone is aware of? Thanks!</p>
