In our application, we are using responsive images by setting up except image resolutions in the custom template. We are having trouble while making an animated webp format image responsive. While adding the original image to the excerpt images, the size of the images is becoming heavy which should not be the case, rather the size should go down to make use of responsive images in an effective way.
