Hello,
This issue is caused by Chrome browser image downscaling. To fix this you need to serve proper image size depending on the image container in which it will be placed. For example if your image will take up 118×118 (https://prnt.sc/xjtca5) space on the page you need to use an image with similar, or very close size (for example 118-150px width).
As an alternative you can add the following code snippet to the Custom CSS area in Theme Settings to improve image quality of downscaled images
.wpb_single_image,
.category-image-wrapp {
image-rendering: -webkit-optimize-contrast;
}
Best Regards
