Optimize your images with TinyIMG

What is a responsive image?

Responsive images automatically adjust to fit the size of the screen, providing a better experience for shoppers across different devices and loading quickly.

These images are set up with a set minimum size range and automatically resized based on the device they are being viewed on. This has a huge impact on your user experience, ensuring that your webpage doesn’t break from an unoptimized and rigidly set image dimension. 

Responsive vs non responsive images

How do Shopify responsive images work? 

Let's say that you've set up an image with a specific dimension on your Shopify product page. Now, since you've added this image to your page by viewing and testing it on desktop, chances are that shoppers on mobile may not have a pleasant experience. They may find the image to be too small or have a hard time looking at the details. 

However, if you've made your images responsive, these images would load to adapt to the device the shopper is using. Responsive images adjust the screen size, enhancing the shopper’s experience. 

Best Scale and Size for Image Responsiveness

The size and scale of your images depends on the device that the shopper is on. For best results, upload the highest quality image you have within the 20MB or 20-megapixel limit but at 72dpi.

To ensure that good image resolution doesn’t impact your site speed, use TinyIMG to auto-optimize your images and keep your resolution intact.

Best image scale for mobile

The best image resolution for most mobiles is 640 by 320 pixels. However, as mentioned earlier, make sure that you don’t.

In terms of best practices for your image sizing, the average JPG is 29KB and the average PNG is 16KB. These sizes are to ensure you have optimized images for mobile devices.  

Best image scale for PC

Since your images will open within a full-screen (unlike smaller smartphone screens), size your images at 1500 pixels and leave the other dimension value to be automatically generated. 

Importance of Shopify Responsive Images For a Faster Shopify Store

Images take up a large percentage of space within an average web page. 

Average bytes per page by content type

So, the larger your image sizes, the slower your site will be. Slow sites mean that more users would drop-off seconds into clicking through to your website. In fact, a team at Etsy found an increased bounce rate of 12% on mobile devices when they added 160KB of images to a page.

Since Google’s algorithm uses factors like site’s speed and how users interact with your store to rank different websites, your image sizes would in turn affect your search position. Google would end up moving your Shopify store lower on search results, even if your site has been well-optimized for the keywords that users have typed in. 

The bottom line?

You end up losing potential customers and miss out on the opportunity to be more visible on Google, the one place where you could have captured organic visits easily.

Just take a look at Amazon: The eCommerce giant discovered that 1 second of page slowdown costs them $1.6 billion per year

By setting up optimized images, you can improve loading times on your Shopify store, ensure a better on-site experience, and in turn, improve your conversions.

How to make Shopify image lazy load?

Lazy loading is a performance optimization tactic that loads images as the user scrolls through the page rather than during the initial page load. Your site will load faster as soon as customers land and later load up the images as the customer continues to browse. With this, you won’t be disrupting the customer experience.

You can set up a lazy load on your Shopify images by making changes to your theme liquid code. Do ensure that you are well-versed in tweaking the theme code. You can also work with a Shopify expert to set this up.
