The 9 Tips on How to Optimize Web and Product Images

In this article, we will give you several image optimization tips for eCommerce that will also help improve your rankings on Google pages.

  1. Know the Required Image Sizes of Your ECommerce Platform

ECommerce platforms like WooCommerce, Shopify, BigCommerce and Amazon, have recommended image file sizes and dimensions to maintain optimized thresholds. Let us thus examine the requirements on the collected product photo upload for all major eCommerce platforms.


  • Ideal Upload Size: 4472 × 4472 pixels up to 20 MB of file size.
  •  Sizes: 2056 x 2056 pixels recommended
  • Zoom size minimum: 800 × 800 pixels
  • Can be JPG, PNG, GIF, TIFF, BMP File Formats


WooCommerce is just a WordPress plugin for your site. It has no platform for itself. It just turns your WordPress site into a website for eCommerce.

Thus, for product pictures, there is no fixed set of guidelines. For the photo upload requirements, you need to check your WordPress theme directives.

  •  Lowest possible size to expand: depends on WordPress theme
  •  Size: 2056 pixels broadly recommended.
  •  The file size is limited to 64 MB.
  •  Size of file recommended: 100KB
  •  Image framework: 85% of the frame should be completed by the product
  • File format: JPEG, PNG, GIF or TIFF files can be uploaded.


  • Uploading size Maximum: BigCommerce declared nothing
  •  Sizes: 2056 x 2056 pixels recommended
  • On the longest side, the minimum size to zoom in is 1,000 pixels
  • JPG is recommended for file types.


Magento is a platform that can be personalized too. It’s a sort of software that installs on your web server, unlike Shopify and BigCommerce.

But it doesn’t have to run WordPress, unlike WooCommerce. Thus, for product pictures, there is no fixed set of guidelines. For the photo upload requirements, you need to check your WordPress theme directives.

  • Zoom in the least size: it can be modified
  • Size: 2056 pixels broadly recommended.
  • Size of file recommended: 100 KB
  •  Image framework: the product should fill 85 per cent of the area.
  •  File format: TIFF, GIF, PNG, or JPEG files can be uploaded.


  •  Upload maximum size: nothing Wix specified
  • Size recommended: the longer side is 1200 pixels
  • File formats: Nothing that Wix defines
  1. Save Your Images Using the Correct Image Format

The 3 most common file formats for images on the web are .jpg, .png, and .gif. Here’s a quick summary of each image format and when you should use it.

  • Gif: A format that can be animated which makes it the first choice for smileys or short videos, but its palette of only 256 colours limits its quality. Use this format for very small images or animated images.
  • Jpg or .jpeg: Is a format using destructive compression which means that the image weight is reduced by removing data that is hardly visible to the naked eye. Use this format for displaying product photos, illustration images, etc.
  • Png: Because it provides lossless compression, this is the best image format compromise. The photos are somewhat heavier than that of a .jpg but retain their quality, making it an appropriate format. Also, use format should another image contains text or if you want a translucent backdrop.
  1. Limit Your Image File Sizes

You can use tools to remove data hidden in your files that have no impact on the visual quality of the images. However, it is necessary to assess your compression rate and consider image resizer tools as well. Indeed, too high a compression can degrade the quality of your images.

  1. There are two types of compressions:

Lossy or Lossy compression is a format in which some data is lost. You can greatly reduce the image, but the quality will be degraded.

Lossless or Lossless compression can reduce an image without losing quality but is suitable for larger files.

  1. Set up a Standard Naming Convention to Organize and Rename Your Images

It is always clearer for you to work with images whose names are explicit: prefer “bushido-desk-mat-black.jpg” to “P123456.jpg”. It is the same for the search engines which will rely on these names in the context of image requests.

It will therefore always be more relevant to set up images with keywords composing their name. Be careful not to create names to lengthen, under penalty of being suspected of “stuffing” keywords.

As in SEO, you always have to be measured and reasonable. Do not expect image SEO miracles for your pages, this recommendation has a very low impact on search engine algorithms.

The names of the images must not contain accented characters or special characters (é, à, ç, +, *, # …), which can be misinterpreted in certain technical contexts, resulting in an image not being displayed, which has a bad effect for the visitor but also in the eyes of search engine algorithms. So: “SEO.jpg” => “referencement.jpg”

  1. Add ‘alt tags’ to Your Images

As a reminder, the “Alt” tag in HTML or the description of the image in editors is a relatively important area for search engines to analyze the content of the page.

This is also a quality criterion for SEO: A page that only contains images with an empty “Alt” tag will be rated less well than a page with “Alt” tags filled in.

So taking care of the description of the images will be beneficial (a little) for your SEO.

This is an opportunity to simply describe the image in natural language, again without keyword stuffing.

  1. Submit an Image Sitemap on Google

A site map is really a document that offers extensive information to search engines about all pages, their connections, and their substance (images, videos, etc.). It enables Search engines like Google to scan a site more intelligently.

Each component in the checklist is immediately connected to the site’s related areas. Sitemaps are generally suggested for all websites, however tiny showcase locations only with very few links may be omitted. Large websites have every reason to establish one in order to increase the crawl of their pages by search engines.

The sitemap also is suggested for websites with flaws in their underlying mesh. Some pages could be tough to locate due to the fact that they are rarely organically connected.

The sitemap is especially beneficial for new sites with very few backlinks, which discourages Google from crawling the full site.

Be cautious: while it may be enticing to apply the shorthand sitemap = crawling all pages, that has mainly an oblique effect. It merely assists Google in finding the sites, but it’ll be the only arbiter of their value and the utility of indexing such.

That said, by uploading an XML sitemap into Google Search, you are essentially telling Google whatever sites you regard to be high-quality.

If they truly are, you have all the odds in your favour that they will appear inside the SERPs.

Please keep in mind that Google has not established a separate sitemap file type for photos, but it does accommodate images throughout the conventional Google sitemap format (in XML version).

  1. Optimize Your Product Thumbnails

Insert bright and good quality thumbnail images. There is nothing more annoying than a tiny thumbnail that barely helps identify a product.

When your customers are reviewing the products on your site, give them the ability to see them correctly, in a quality size and resolution.

Don’t forget about mobile users! Viewing the correct size and good quality image gives them a better mobile experience.

  1. Conduct A/B Testing on Your Product Images

A/B analysis is among the most successful methods for increasing conversion rates. Performing an A/B analysis is a highly valuable component in many business apps, and starting up a system is simple.

A/B analysis is delivering two copies of the very same material (for instance, a home page, call-to-action, or email) to 2 different audiences of similar size in an effort to evaluate the efficacy of each version.

Graphics, like words, play an essential role in online content. As a result, they are among the key aspects to be examined. Then that’s a matter of fine-tuning their size, brightness, and placement on the webpage.

  1. Use a White Background for Your Product Images

The key to successful photos is to use a transparent background. The white background enhances your products and produces much better quality photos. It also helps to ensure that the white balance is in focus, which helps your product colour to be better.

It is advisable to use a curved white background which allows a better rendering of the volumes. For small products, place the installation on a table, to have the flexibility and to be able to better adjust the brightness.

You will find tables on the market specially designed for taking pictures. Otherwise, you can use any table that is stable and allows you to install your white background.

For larger products, things are a bit more complex in terms of photo editing. If you plan to take photos regularly, you can buy a white backdrop commercially.

It will make your life easier. Otherwise, use a large sheet of white paper and find support for stabilization.
