A nice looking image can be harmful to your website if it's not optimized. It's important to optimize images for the web because the fewer bytes the browser has to download, the less bandwidth the client uses, and the faster the browser can download and render your content on the screen.

The first thing is to save your graphics in the right format and size. After that, you should run an image optimizer.

Some tips and techniques to keep in mind as you work on optimizing your images:

  • Remove unnecessary image metadata like geo information, camera information, and so on
  • Use automated tools to ensure that all of your images are always optimized (E.g.

If your website is running on WordPress you should install and activate the plugin WP Smush. It scans every image you upload – or have already added to your site – cuts all the unnecessary data and scales it for you before adding it to your media library.
