Blurring Images

My Woocommerce store images are blurring see link https://w.warrimarket.com/product-category/electronics-stores/. I did a search and found this guide from Woocommece.

Fixing Blurry Product Images
There could be a few things dictating your image dimensions when using WooCommerce. But the first and likely culprit comes mainly from your theme. It’s design, at max size, has specific image dimensions measured in pixels.

Thus the dimensions you specify at WooCommerce > Settings > Products > Display should match or be higher. The settings here affect the size of the images your theme uses when displaying product images. Again, they do not change the size the image is rendered at.

When your product images are blurry there are two things that could be happening. One, your image size settings may not be adequate (too small) for your theme. This can cause problems as your theme wants an image at 800 x 800 pixels, but you are giving it one at 400 x 400 pixels.

Two, the original images you uploaded aren’t high enough resolution. Even if your image settings are right, the original image source is too small. The only thing you can do in that cause is re-upload appropriate sized images to begin with. Anything at 800 x 800px or higher would work for most themes. We show you how to find the max image size your theme wants in the video and below.

Please kindly advice on how to correct this?
