How to use ShortPixels Image Optimizer


  1. Log in to your WordPress Dashboard.
  2. On the left-hand side menu, go to Media.
  3. Change the menu structure to List. To do this, click the small list icon rather than the grid icon on the top left above Bulk Actions (indicated with the orange outline below).
  4. As indicated in the orange outline below, there is a three-lined icon that you can select.
    • Within this, there are three ways an image can be transformed when it is compressed:
      • Lossly: The best option for most users. The images processed with Lossy algorithms are the smallest optimized images you can get. So, if the speed of your site is paramount and you want the best balance between optimization and picture quality, we recommend you continue to use Lossy optimization.
      • Lossless: Images are pixel-by-pixel identical to the originals, but they offer a smaller size reduction compared to either Lossy or Glossy processed files. If you want your image information to remain untouched, while slightly reducing image size, then select this option.
      • Glossy: The best choice if you care about Google PageSpeed Insights or GTmetrix but you believe that a slight loss of page speed is an acceptable compromise for top-notch image quality.
    • Images are automatically transformed into Lossly images when they are compressed. However, you have the choice to change them to Lossless, Glossy, or Restore Back-up (original file). For what it’s worth, we typically recommended using Lossly for all images, unless they have text (e.g. phone number) in them in which case we recommend Lossless.
    • There is also a Compare option that allows you to slide between the two images to see which version you prefer.
    • It is also valuable to see how much the image is compressed. As you can see below, the three images were compressed by about 50%.
