title: PNG Compression
body: <p>Some PNG images although just 150px x 160px wide have 60KB filesize. I've already run them though optimizers (ImageOptim for Mac) but that didn't help much. </p>
  
  <p>Is there any way to compress it further, either manually or using some other tool? 60KB for a normal 150x160 image is really unacceptable and I can't use JPG or GIF there because I need transparency.</p>
  
  <p>I tried exporting the PNGs as <strong>8-bit PNG</strong> and the filesize has reduced significantly!</p>
