title: PNG to eps conversion massive increase in file size
body: <p>I'm converting an image from .png to .eps and it hugely increases the file size.
  Can anyone explain why this is, and how to prevent it increasing so much.</p>
  
  <p>I'm using Unix <a href="http://www.imagemagick.org/script/convert.php" rel="noreferrer">convert</a>: <code>convert image.png image.eps</code></p>
  
  <p>Thanks for any help</p>
