Featured image resolution of blog posts on the homepage

The thumbnail images for the featured images of blog post get blurred (and/or not as high res as stock photos) on home page. What should I do to fix them? EWWW Image Optimizer and I disabled it. I don’t use Jetpack at this time but eventually, I’ll need it. How can I use Jetpack and not get my featured images blurry?

I attached two screenshots. The red circle is my own image. The blue circle is a stock image that came with your template. They, both, have the same resolution. The images that I uploaded look not as clear. How can I make sure that they are crisp clear? The resolution is very similar. I used low and high resolution, the result is the same.

Thank you!
