The GTmetrix report for my website shows that the pagespeed is slow because server scaled images.
The featured image size, that I have been using in the post is 800 x 400.
In media settings also, I have set the large size image size to 800 x 400.
In home page, I have displayed some of my latest posts. The images on this homepage has a smaller size of the featured image.
The report shows that “the image is resized in HTML or CSS from 800×400 to 265×133”.
How to resolve this issue?
Could you please help me to resolve.
