Imagine slashing your website’s load time in half just by optimizing for faster image loading – it’s not magic, it’s science!

By compressing your images without losing quality, you can significantly speed up your website, improve engagement, and lower bounce rates. Quick image loading is important for beating rivals and keeping users happy in today’s fast online world.

In this post, we’ll explore image-related issues, offer solutions, and introduce a free service for image optimization. Get ready to sprint past your rivals with fast loading images!

Are Images Loading Slowly?


Your web page should load in just a few seconds, ideally 2 seconds or less. If you are using large, uncompressed images, your website is likely to have a slow loading speed.

Unfortunately, web pages keep getting bigger over time. Image data is the biggest contributor to the size of a typical web page.

Slow loading images are a common problem on websites and can seriously harm your search engine rankings. Images sizes vary depending on a range of factors such as:

  • File format (JPEG, PNG, GIF and other formats)
  • Dimensions (width x height)
  • Compression level

Additionally, non-image factors can affect the load times such as:

  • Hosting service
  • Speed/bandwidth of web server
  • Using a CDN (Content Delivery Network)

As you can see, there are many factors that can impact the size of your images and how quickly they load.

Even if your website loads quickly for you, it may be slow for visitors from different regions or countries. If your website targets a global audience, it’s advisable to consider using a CDN (Content Delivery Network) to improve website speed in other countries.

How can you speed up image loading on your website?

They are several techniques you can use:

  • Use the correct image format
  • Properly size your images
  • Compress your images
  • Offload serving images to a CDN (Content Delivery Network)
  • Use a lazy loading plugin to load images only when they scroll into view

Implementing these techniques can significantly improve the loading speed of images on your website.

Image Formats

Different formats should be used for different types of images. JPEG is great for photographs, while PNG is better suited for illustrations or drawings. GIF is commonly used for animated images.

Newer formats like WEBP provide even greater compression without compromising image quality. Consider using WEBP format for improved optimization.

Properly Size Your Images

The average smartphone has a horizontal display of 400-500 px, any images with a greater width will either cause horizontal scrolling or will be resized by the browser resulting in wasted bandwidth.

Automatically resizing your images can reduce download time and speed up page loading.

Properly Size Your Images

Compress Your Images

Compressing images doesn’t change the width and height of the image but reduces the file size. Different compression methods can be used including lossless methods that don’t reduce the quality of the image.

Use a CDN

Enhance your website’s image loading speed by leveraging a CDN (Content Delivery Network). Hosts like SiteGround offer easy CDN integration, distributing your images across a global server network. This setup not only results in speedy image loading but boosts all static files resources (such as CSS, fonts and javascript files).

Lazy Loading Plugin

Install a lazy loading plugin to achieve fast image loading on your website. These plugins ensure images load only when in view, reducing initial load times and enhancing user experience. As images load when needed, your site’s speed improves significantly. The SiteGround optimizer plugin offers a free solution for lazy loading on all WordPress websites, streamlining image display and boosting site performance.
