An app to create an image from first page of PDF
<p>Can anyone recommend an app that will create an image for any given pdf.  This is for a website, the site already has thousands of pdfs stored.  I only wish to create the image of the pdf as and when I need it.  </p>

<p>For example a webpage will check a list of ten pdf's, if no image available then create one.  So I am not interested in a tool that converts pdfs by file location, I want to be able to call it when needed to create the image.  Ideaaly i would like to have some control over quality and size of the image created.</p>

<p>Any help would be much appreciated?</p>
