by Lily Tran

There is a saying that “a picture’s worth a thousand words”. When it comes to website images, the same is true. Images provide your products or services a more in-depth look than words alone can ever hope to achieve. Hence, image is very important.

Store owners always have to find the best way to optimize their photos. If you are one of them, don’t skip this blog because it shows you all the necessary information

Let’s read now beginning with how Magento 2 images impact the business!

How do Magento 2 Images Impact Your Business?

Website Performance 


Website performance mentions the loading page speed of the website. It’s how quickly the pages of a website load and display in your web browser.

In many factors impacting the performance of the websites, you can easily find image and file size is a big problem. Large photo and video file sizes will slow your website down. The data needs more time to load your large images on your website. 

For example, while loading the compressed file, at 0.08MB, the visitor will see it instantly, but a 15MB image on a 3G connection can take 17 seconds to load, and that’s a 18,650% increase in waiting time.

Hence, optimizing Magento 2 images is a fast way to enhance website performance. Use Google’s PageSpeed Insights tool to evaluate the performance of your website and discover where you stand.

Customer Experience


Image size affects website speed and website speed impacts the customer experience. According to a report, 40% of users abandon sites that take longer than 3 seconds to load.

Second, a high-quality image not only conveys your brand’s professionalism but also encourages customers to stay and make more purchases. With online shopping, the Image gives a specific look about your goods or service while purchasing online, and it is a key element in persuading people to buy and make repeat purchases.

Last but not least, user experience also is impacted by image responsibility. Mobile commerce statistics say that in 2021, 72.9% of all online sales came through the mobile channel, and mobile makes nearly three-quarters of all online sales. With the increase of smartphone users, images are required to be responsive to all devices, especially smartphones. 

Hence, directly or indirectly, image impacts the customer experience.



Images take up over 60% of modern websites’ total bandwidth. With the large image quantity,  the first touchpoint your buyers come into contact with on your website can be the image, and that experience can make or break their perception of your brand.

Product photos and SEO images play an important role in SEO, conversion and sales, visitor retention and more. 

  • According to a study by Search Engine Land, Images often have a much higher CTR (Click-Through Rate) than text-only SEO search results, with the exception of the first position.
  • Sheila Dahlgren, senior vice president of marketing at Scene7, provider of on-demand rich media, said that “Customers are three times more likely to buy online when retailers offer rich imagery with the ability to zoom, pan, and see color options and alternative views of the merchandise, along with the products presented in context or on a model”.

Hence, to build a business with an outstanding website, you should focus on optimizing all images on your website. You can receive amazing support from Magento 2 image optimization extension list below!
