Images are an essential component of your Magento e-commerce site. The proper use and optimization of product images can make a HUGE difference between a storefront that enhances user experience, and one that does not facilitate conversions or sales.
A picture is worth a thousand words and as a marketer, you cannot ignore the key role visual search plays in influencing buyers’ purchase decisions. Usually, when a customer visits an online store to search for a specific product, they scroll through the store’s product listing to identify their desired product with an image.
After identifying the product, their next step would be to read through the product description to confirm that it is truly what they want. Thus, the need for store owners to optimize all product images, ensuring that they have the proper image title, alt text (or alt attributes), are of high quality, and appropriate file size.

In this ultimate guide to product image optimization in Magento 2, I will discuss all the information you need to know about the process. Magento Performance Optimization: A Complete Guide On Product Image Optimization. There are several different techniques you can use to optimize product images on your Magento e-commerce store.
Each of these techniques varies in its application and requires a different level of technical expertise and skill. The techniques used will depend largely on the type of image you need to optimize and your specific needs.
Below I will discuss the different product image optimization techniques for you to know which one of them will be best for your specific needs.
Optimize the size of the product images
Image size is a principal parameter you need to focus on during the optimization process, as a properly sized image can help to save cellular data, improve load time, and prevent delays.
A major factor that influences an image size is its resolution- which is usually described in Pixels Per Inch (PPI) and refers to the number of pixels per inch of an image. Image resolution can be identified by the width and height of an image plus the total number of pixels.
For instance, an image that is 2058 pixels wide and 1500 pixels high (2058 × 1500) contains 3,087,000 pixels or 3 Megapixel.
Scale Or Resize Product Images
Images are essential to show your products to buyers and also enhance the design of your Magento store to make it more appealing. However, the images should not be too large as it will lead to a slower page load time, neither should it be too small as it will end up blurry.
Therefore, before you add images to your Magento store, you need to resize them to be in tune with Magento’s own size requirements for product images. To meet this requirement, image sizes should be no more than 1920 pixels (px) high and 1200 pixels (px) wide.
Before making and adding product images to your Magento 2 store you need to take into account that any product image with dimensions above these figures will end up distorted. Sticking to these Magento’s image specifications, you can scale your image to the appropriate sizes in line with Magento’s requirements without sacrificing image quality.
Choose An Efficient Image File Format
The image file format is also another key parameter that affects the performance of individual product images on your site. There are different image formats such as PNG, JPG (or JPEG), SVG, WebP, etc each one with its own strengths and weaknesses.
But it is important that you choose and use an image format that is well optimized and valid. But how do you know which one to choose? There has been a lot of buzz around WebP, which is one of the newest image file formats created and rolled out by Google.
WebP image file format combines the compressibility of jpegs, as well as the quality retention and transparency of pngs. With the use of WebP image file format, you can create high quality transparent or non-transparent images that are very small in size.
This will benefit you in terms of faster page load times and optimized performance of your e-commerce site. However, despite all the incredible features of the WebP image file format, it is currently not supported by browsers like IE, Safari, iOS Safari, Blackberry Browser, kaiOS Browser.
While these are not major browsers, choosing and using only the WebP image file format will display a broken image to users who visit your site using any of them, which is bad for the user experience.
To be on the safe side, it is best for you to create an image fallback so that, if the browser cannot load the WebP image source, then it will automatically select and load an alternative file format option, instead of showing a broken image.
