Images are a SO important to the look of websites and can make a significant impact in the success of our sales. Images set the tone for designs and even contribute to the success of your SEO on Google, but what happens when they slow down your site’s performance?

Here are a couple of ways that you can resize your images to make sure they still maintain their amazing quality, but don’t hinder your online presence. The best part, it’s an easy fix!

When should you resize your images?

Images these days can take up over half of a website’s total size. With that, it is important that images are mindfully resized and formatted to maintain the website experience. Any images in megabytes (MB) are going to be considered too large. The goal is to resize images so that they are around 500 kilobytes (KB) in size. Once you know the size, you can determine if it needs to be compressed or reformatted.

Here is how you can find out the size of your image:

  1. Go to where your image is located on your computer

  2. Right click the image thumbnail

  3. Click on “Get Info”

  4. Notice the size of the image is listed on the top right hand corner

    (See example below)

Option 1: Convert PNGs to JPGs (on Mac)

A PNG stands for Portable Networks Graphic and is generally a larger file size than JPGs (Joint Photographic Experts Group). The biggest difference is they have different compression formats, but both can successfully be used on websites.

An easy way you can make the file size of your PNG smaller, is to convert it to a JPG.

Here’s how:

  • Open your image in preview
