If you're experiencing blurry product images on your WooCommerce site, it's likely because WooCommerce automatically adjusts the image size for improved performance. However, if you want to enhance the image quality and prevent blurriness, you can increase the image dimensions. To do so, go to your WordPress customizer > Locate WooCommerce > Product Images, there you will see Main product image, increase its dimensions. By increasing the dimensions of the main product image, you can improve the quality of your product images and eliminate blurriness.
