What is this functionality used for and why do we set it up?

Many people nowadays want to make a quick profile pic that is round. Often though, they don't have design software like Photoshop installed on their computers.

This post teaches you how to use an app that is already installed on your Macbook. It is called Preview and using it, you'll be able to make round profile images in less than 30 seconds. You can then apply your new image on your Ghost blog. (or anything else for that matter)


  • The recommended OSX app to use is the built-in app, Preview
  • This will not work on a windows computer as Windows doesn't have the Preview app installed
