title: Pdftohtml Poppler utils not working on centOs
body: <p>I am trying to convert pdf to html in php using mgufrone library(<a href="https://github.com/mgufrone/pdf-to-html" rel="nofollow noreferrer">https://github.com/mgufrone/pdf-to-html</a>). I run this in my mac it's working alright. 
  But when I run in centos server, the .html file is created blank inside /vendor/gufy/pdftohtml-pdf/output folder.
  In my mac local multiples files are created inside /output folder. But in server only a single file is created with empty content. 
  Please help.</p>
