Many factors must come together for a professional website design to be appealing and functional. Today, images are a crucial component of every website, but depending on how they are used, they can benefit or harm your website. Magento 2 image sizes and how it influences the site is a noteworthy aspect.


Types Of Image In Magento 2 Store

To gain more customer attraction, it is vital to upload photographs and other media kinds; however, this step slows down the site’s loading time. After that, it includes a bad user experience and a high bounce rate.

In another way, the changes will be reflected as desired when you run the following command:

Go to System > Tools > Cache Management to access this menu. Then, to clean Magento Cache, click the Flush Magento Cache button.
Everyone knows how vital page load speed is to effective website design and how it influences SEO, page rank, and conversion rates. Even if the image looks small on the website, its size file impacts how quickly a page loads. 
Next, find the Advanced section and click System.
View.xml contains almost all of the configurations for the product image (including width and height). Therefore, you must modify the view.xml file if you wish to update or resize product images in Magento 2.

Here, you can select the maximum permitted width & height for the product images and whether or not to activate frontend resize. In your Media Gallery, optimized images are generated automatically and take the place of your original images.

Magento 2 default allows you to resize unnecessarily large images automatically. You can freely config the maximum allowed width and height of the images. When not needed, you can also disable the feature.
You can alter the width and height of any “image id” in this file to your taste.

We suggest using Magento 2 Convert Images to WebP if you’re unsure about the images you should submit (like .jpg, .png, .svg, .gif, etc.). A popular photo format on the internet today, WebP provides improved lossless and lossy compression since they are 26% smaller when compared to PNGs and 25–34% smaller than equivalent JPEG images.

As a result, for the most practical, we suggest you resize Magento 2 images by default and use Magento 2 Convert Images to WebP to convert the types of the image files. 
Moreover, optimizing Magento 2 image sizes enhances your SEO when used with a top SEO strategy. It’ll be more prominent in search engine results for your website.

Otherwise, find the view.xml file in your parent theme’s etc/ folder and copy it to your theme folder if your theme doesn’t already have one. This adheres to Magento’s fallback system.

The base image serves as the page’s primary illustration. It is the most substantial and superior of the four sorts. Customers can click to enlarge the image if the one you upload is larger than the image container. Viewers have a two-to-three-fold zoom-out option. 

By Magento 2 default, the base image is the most prominent image on a product page, and Magento displays at appropriate 700 x 500 pixels. Therefore, it is unsurprising that Magento 2 demands the maximum resolution of photos compared to other image versions.


<images module="Magento_Catalog"> <image id="category_page_grid" type="small_image"> <width><!-- Replace this with width in px : 300--></width> <height><!-- Replace this with height in px: 450 --></height> </image>

Step 4 – Clean the cache

This extension streamlines and accelerates the WebP online conversion procedure. With just one easy adjustment, every image on your Magento 2 site will be converted to WebP, eliminating the need for manual format changes.
<images module="Magento_Catalog"> <image id="unique_image_id" type="image_type"> ... </image>

First, go to Stores > Configuration.
We recommend this product image type’s dimensions for 250 pixels wide by 250 pixels in height.
