  • PNG: This image file type is perfect for images with transparency like logos and graphics.
  • WebP: You can use this image file type for better compression. Also, it can provide you with smaller file sizes and faster loading speeds.

Shopify suggests using JPEG for product images, pages, and blogs. On the other hand, you can go for PNG for logos, trims, and borders.

Well, you can also go for GIF images, but these tend to reduce the loading times of the Shopify store. unless and until it’s necessary to go for dynamic elements, you must not consider using GIF images.

2. Compress Images

Shopify Compressed Images

It is crucial that you must always compress images and get your Shopify store speed blazing fast. You must always aim for file sizes of 70 KB or lower for great loading speed. You can even go for higher than this file type, but this depends on the image quality you need.

So, there are two basic ways of resizing or compressing your images. You can go for:

  • Lossy Compression: It will result in the loss of some data, quality, and size of the image.
  • Lossless Compression: It reduces the size of the image without affecting the quality. You can use apps like Adobe Photoshop, Pixlr, and Canva for this purpose.

Being a Shopify merchant, you don’t have to worry much about compressing the image sizes since the theme you’ll be using compresses the images automatically. Still, you must keep in mind that your images should be under 70KB.

3. Use Correct Image Dimensions

Shopify Image Dimensions

If the images on your Shopify store are either too large or small, it can hurt the SEO rankings and page loading times. Thus, you must ensure that you’re using the right image dimensions for each type of image in your store.

Product Image 2048 x 2048 1:1
Collection Image 1024 x 1024 1:1
Logo Image 250 x 250 1:1
Banner Image 1920 x 1080 16:9
Slideshow Image 1920 x 1080 16:9
Text Overlay Image 1920 x 1080 16:9
Background Image 1920 x 1080 16:9

No doubt, decorative images can help improve the aesthetic appeal of a Shopify store, but they can also result in a slow load speed of the site. Thus, you need to consider the decorative images such that you don’t miss out on the ability to convert visitors into customers.

Furthermore, you also need to check the file sizes of decorative images and consider using a template in place of that to minimize the file sizes.

6. Use Image Sitemaps

Shopify Image Sitemaps

An image sitemap is an XML file that includes all images of your Shopify store for search engine crawlers. It allows Shopify merchants to target specific images for search engine crawling and indexing, which can then be found easily by prospective customers.

Having an image sitemap can help ensure the Shopify merchants that their images are listed correctly on various search engines. This way, you can also reach out to more targeted audiences since your Shopify store’s images will show up in the right places.

In addition to this, Shopify merchants can even optimize their Shopify store for particular keywords using the image sitemap.

7. Minimize HTTP Requests

Shopify Minimize HTTP Requests

HTTP requests are when your browser and server communicate with each other when you visit a website. Every time you open a new page on a website, an HTTP request is sent from your browser to the server.

Thus, you need to be careful of the number of HTTP requests while using Shopify images. Reducing the number of HTTP requests coincidently can help improve the performance of your website and also increase the loading speed.

If you are looking to minimize the number of HTTP requests, you must use techniques like CDN or Content Delivery Network. It stores images and combines many images into one.

8. Create Alt Tags for Images

Shopify Alt Tags for Images

Additionally, creating alt tags for images is an important Shopify image optimization technique that can improve your website’s accessibility and search engine visibility.

Keep in mind that your alt tags should describe what an image is all about. For instance, a tri-colored flower can be described as a “tri-colored flower” or “tri-colored daisy” instead of a “flower with red, yellow, and pink petals”.

9. Use Concise & Direct Image Names

Shopify Image Names

Using concise and direct image names is an essential Shopify image optimization technique that involves giving your images descriptive and relevant file names. This makes it easier for search engines and users to understand the meaning of the images.

To optimize your images using this technique on Shopify, you should follow these tips:

  • Start by choosing a descriptive name that accurately describes the image.
  • Avoid using generic us names such as “image1” or “picture2”, since this doesn’t help with any meaningful information to users or search engines. Instead, use specific and relevant keywords in the image name that accurately describe the content of the image. For example, if the image is of a red dress, you could name it “red-dress.jpg”.
  • Use hyphens (-) to separate words in the image name instead of underscores (_) or spaces. This is because search engines can interpret hyphens as word separators, while underscores and spaces can be seen as part of the word.
  • Make sure the image name is short and concise, without using unnecessary words or characters.

10. Test Images & Make Adjustments

Shopify Image Testing

Testing images and making adjustments is an important Shopify image optimization technique that involves regularly reviewing your website’s images and making necessary adjustments to improve their performance.

  • Look at metrics such as bounce rate, time on page, and conversion rates on Google Analytics to identify images that may be underperforming.
  • Review the quality and relevance of your images. Make sure that they are high-quality and relevant to your store’s content.
  • Test different variations of images to identify the most effective ones. You can test variations such as image size, placement, and format to see which ones perform best.
