Hi SGupte,

It seems that you have provided the custom width of the image to overwrite the original size of image. As per the image original size you need to keep the image in your page, so that there will be no blurry image, for example we have attached the screenshots what we want to say.
As well as you can use the following css to fix your issue;

.page-id-227 img.aligncenter {
    width: 100%;

NOTE: Please use the child theme style.cs or custom css plugin to write the css.
