It helps with search results

Makes it easier for people to use your website
When images are clear and the right size people can understand what they are looking at. This is especially important for things, like clothes, electronics and home items.

Best Image Size for Shopify, Amazon and WooCommerce
Different platforms have different requirements for images and if you do not follow them the images will not look as good as they should.
Shopify Image Size
- The ideal size for a Shopify image is 2048 × 2048 pixels.
- The recommended ratio for Shopify images is 1:1 square.
- The best format for Shopify images is JPEG or WebP.
Shopify will automatically make your images smaller. If you upload images that are already optimized they will look better. This is usually considered the image size for Shopify stores.
WooCommerce Image Size
The size for a WooCommerce image is 800 × 800 pixels. However this depends on the settings of your theme. WooCommerce images can be scaled to fit screens.
If you upload images that are all different sizes it can be hard to get them to line up properly on the page. This is why a lot of sellers like to use WooCommerce product image size settings to make sure everything looks uniform.
Amazon Product Image Size
The size for an Amazon product image is 1000 × 1000 pixels. It is recommended that you use an image that’s 1600 × 1600 pixels or bigger. The image also needs to have a background.

Image Formats for E-commerce Websites
When you are making a website for your store you need to think about the kind of picture format you will use. Choosing the format is just as important as the size of the picture.
JPEG
This format is really good for taking pictures of the products you are selling. The file size is small which is great. It is okay if the picture is not totally perfect, a little quality loss is fine.
PNG
This format is really good for pictures that have backgrounds. You can have high-quality pictures with this format. The file size is bigger which is not so great.
WebP
This is a good format to use nowadays. It is smaller than JPEG and PNG which’s awesome. It is really good, for making your website load fast and for search engine optimization.
The WebP format is now used a lot in ecommerce image optimization strategies because the WebP format reduces the time it takes for your website to load without making the pictures look bad.
