title: Remove all text from PDF file
body: <p>I am using Ghostscript to convert source PDF file into array of PNG images. Before I convert PDF page into PNG image I would need to extract (delete) all text from PDF so that converted page image would contain all other elements, excluding text.</p>
  
  <p>Can I achieve this with Ghostscript or will I need to look into different tools? </p>
  
  <p>I would also be interested in a tool that can read-save my source PDF removing all the text.</p>
