title: How to remove Active Content from uploaded PDF documents?
body: <p>I developed a kind of job application website and I only now realized that by allowing the upload of PDF files I'm at risk of receiving PDF documents containing encrypted data, active content (e.g. JavaScript, PostScript), and external references.</p>
  <p>What could I use to sanitize or re-build the content of every PDF files uploaded by users?</p>
  <p>I want that the companies that will later review the uploaded resumes are able to open the resumes from their browsers without putting them at risk..</p>
