A Good Image for an eCommerce Site

We optimize images by clarifying our goals and understanding what images are excellent for e-commerce websites. The image of a high-quality e-commerce website should have the following characteristics to better attract and retain customers.

High quality

The right quality images can better show the intricate parts of the product. This means that the photos should be clear, visually appealing, and sharp. The product pages of the details will support enlargement, and the images should have a high resolution. 

High-quality images allow users to see all aspects of the product details and help build trust between the website and the customer.

Accurate representation

Images need to match the product description and reflect aspects of the product, such as features, color, size, and shape. They need to be what you see and get, consistent with the product the customer receives. Also, one trick to make your image more captivating is to use a blurred background. The technique allows the product to stand out, potentially catching the viewer's attention immediately.

The product description should mention and emphasize any differences from the actual product received. Avoid unnecessary misunderstandings and give them a clear and accurate understanding of the product they buy.

Multiple perspectives

Multiple-angle pictures facilitate customers to see the product from all angles and thus understand it more comprehensively. Customers who know the product from multiple angles will make a more rational and informed decision about purchasing the product.

Minimize after-sales and returns

Reduce the possibility of after-sales returns by optimizing images on your e-commerce platform. The image display area of a home page is the first thing a customer sees when browsing for products, making it a crucial element of the user experience. 

By optimizing images, you can improve the quality of your website, increase user engagement, and ultimately drive sales. 


The consistency of images is a crucial point. The pictures on the website should be consistent in style, color scheme, lighting, and tone. This gives the user a better overall visual effect of the site and makes it easier to make a lasting impression.

If your style, colors, and image tones just happen to match the user's aesthetic, your website will gain more goodwill. Consistency facilitates a website to build a brand image and look more professional.


All images on your website should be unique. The uniqueness of your photos can make your webpagestand out. Essence better enhances the competitiveness of your online platform. 

It impresses your customers and stimulates their curiosity to explore your site. Staying on the site longer to learn more about your products gives your digital platform more opportunities. 

A unique online presence helps build brand originality and credibility, which increases customer loyalty and repeat business.

Optimized for web

Optimizing the images used for the web can enhance the performance of your website. According to a study by Amazon, for every 100ms delay in page load time, they saw a 1% decrease in sales.

More load times and higher image download speeds. This facilitates providing a more positive website experience to the users. Retaining them is also getting opportunities.

By optimizing images for the web, you not only improve website performance and create a positive user experience, but you also increase the likelihood of retaining visitors on your website. 

When users have a good experience on your website, they are more likely to spend more time exploring your products or services, which increases the chance of converting them into customers. 

By retaining visitors to your website, you are also creating more opportunities for them to engage with your content, whether it be through social media, email newsletters, or other marketing efforts. However, make sure that all your content corresponds to your brand message and tone, manage social media accounts in one place, and share your campaigns and promotions in the same style on all platforms.

5 Best Image Optimization Tricks

We clarify the characteristics of a good photo for an e-commerce website. Let's see where to start with optimizing pictures.

1. Ensure the Right Image Format

Using the appropriate image format can reduce image size by up to 80%, resulting in faster loading times that can lead to a 7% increase in conversions for every one-second improvement.

The right image format can improve the visual quality of your website and also enhance its performance. Choose between JPG, PNG, and WebP formats: JPG for images with multiple colors and PNG for images with transparent backgrounds. 

Webp combines the advantages of both formats and is smaller in size for the same clear image. This is because it provides better compression without compromising the quality of the image.

2. Compress Images for Efficiency

A survey by Kissmetrics found that 47% of consumers expect a web page to load in 2 seconds or less, and 40% of visitors will abandon a website that takes more than 3 seconds to load.

Compressing images is all about reducing the image's size and shortening the improved website's loading time. You can easily find various image compressors just by searching in Google engine. 

What needs to be clear is that we are looking for a balance between file size and image quality rather than just going for smaller image sizes. 

3. Maintain Proper Picture Quality

Maintaining the image quality during the uploading or compression process is very crucial. Prevent over-compression and ensure the images are saved at the proper resolution.

Verify that the quality of the images does not degrade during the upload process. Then you need to adjust the quality of the image before uploading. Ensure that the final rendering of the image is as expected.

4. Optimize Alt Text for Accessibility

Alt text is a description of the image that will appear instead of the image if it fails to load. Web admins should use descriptive and concise language to provide a clear understanding of the image. 

It is vital to provide alt text for each image on your site to ensure that visually impaired user can understand its content. Or if the image appears to fail to load, the user can understand the image based on the text.

5. Use Descriptive File Names for SEO

Product image file names affect the visibility of products and websites in search engines. Naming image filenames using relevant keywords allows search engines to understand the image and related information better. 

This improves the ranking and visibility of the product in search results. Of course, this is also a way to optimize the ranking of your website.
