Shopify website performance is crucial for user engagement and conversion optimisation. One often overlooked aspect that significantly impacts website performance is the size of the images used. Large, uncompressed images can slow down page loading times, leading to a poor user experience and lower search engine rankings. This is where image compression comes into play. In this article, we will explore why compressing images is essential, the difference between resizing and compressing images, and some handy apps you can use to optimize your Shopify website's images.

Why Compress Images?

  1. Faster Loading Times: Large images can drastically slow down your website. Compressing images reduces their file size without sacrificing quality, ensuring that your pages load quickly. Faster loading times lead to better user experiences, reducing bounce rates and increasing the time visitors spend on your site.

  2. Improved SEO: Search engines prioritize websites that load quickly. By compressing images, you improve your site's performance, which can lead to higher search engine rankings. This means more visibility and more potential visitors.

  3. Reduced Bandwidth Usage: Compressed images use less bandwidth. This is particularly beneficial for users with limited data plans or slow internet connections. Additionally, it can save costs on your hosting plan, especially if your website has high traffic.

  4. Enhanced User Experience: Visitors expect websites to load quickly and smoothly. Slow-loading images can frustrate users, causing them to leave your site. Compressed images ensure that your website provides a seamless experience.

Resizing vs. Compressing Images

While both resizing and compressing images aim to reduce file size, they achieve this through different methods and serve different purposes.


  • Definition: Resizing involves changing the dimensions (width and height) of an image.
  • Purpose: This is useful when the image is too large for the intended display area. For example, an image taken at 4000x3000 pixels is resized to fit into a 800x600 pixel space on your website.
  • Effect: Resizing reduces the file size by reducing the number of pixels. It’s essential for maintaining proper aspect ratios and ensuring that images fit the design of your website.


  • Definition: Compression reduces the file size by reducing the amount of data in the image file without necessarily changing its dimensions.
  • Purpose: This is ideal for maintaining image quality while reducing file size. Compression can be lossless (no quality loss) or lossy (some quality loss for smaller file size).
  • Effect: Compressed images retain their dimensions but are lighter, leading to faster loading times and reduced bandwidth usage.
