We can do a lossy compression of our image. Reducing an image from 2MB to 400KB is already a significant improvement. A good place to start is ImageMagick's resize documentation: Resize or Scaling (General Techniques).

Some of you may think 50% is too small - if that's the case, feel free to play around with the resize option. That's a 80% reduction for a short one-line command! The file size is also reduced down to about 430KB. Running the convert command above reduces the dimension to 1792 x 1015. In my case, the resulting screenshot is 2.1MB and has a dimension of 3548 x 2030. Click on the window that you want to take a screenshot on. Try it!
