Try this:

imageView.sd_setImage(with: URL(string: imgUrl), completed: { (image, error, cache, url) in
                let imageSize = image?.size
                print("imageSize", imageSize)
                var imgData: NSData = NSData(data: image.jpegData(compressionQuality: 1))
                // var imgData: NSData = UIImagePNGRepresentation(image)
                // you can also replace UIImageJPEGRepresentation with UIImagePNGRepresentation.
                var imageSizeBytes: Int = imgData.count
                print("size of image in KB: %f ", Double(imageSizeBytes) / 1000.0)
            })
