title: How to compress a pdf with node?
body: <p>I have found:</p>
  
  <ul>
  <li><a href="https://www.npmjs.com/package/scissors" rel="noreferrer">scissors</a></li>
  <li><a href="https://github.com/lpatters/pdfspin" rel="noreferrer">pdfspin</a></li>
  </ul>
  
  <p>They both rely on <a href="https://www.pdflabs.com/tools/pdftk-server/#download" rel="noreferrer">PDFTk</a>, which costs around $1,000.</p>
  
  <p>Where can I learn more about pdf compression with node, or find the already made library ?</p>
