title: imagemagick resizing and quality PNG
body: <p>In my application I need to resize and make the quality on PNG files poorer. </p>
  
  <p>In full size the PNGs are 3100x4400px using 2,20MB disk space. </p>
  
  <p>When running the following command:</p>
  
  <pre><code>convert -resize 1400 -quality 10 input.png output.png
  </code></pre>
  
  <p>the images are resized to 1400x2000 using 5,33MB disk space.</p>
  
  <p>So my question is: How can I reduce the file size? </p>
