How to crop the bitmap and save it in its original quality?

Rectangle rectangle = new Rectangle();
rectangle.Height = 100;
rectangle.Width = 100;
rectangle.X = 100;
rectangle.Y = 100;

Bitmap temp = new Bitmap(varas.ptval, varas.ptval.Width,varas.ptval.Height);
temp = varas.ptval;
var croppedImagem = cropBitmap(temp, rectangle);
croppedImagem.Save(paths + "\\" + "SPR_" + i + ".jpeg", ImageFormat.Jpeg);
                           

 public static Bitmap CropBitmap(Bitmap bitmap, int x, int y, int w, int h)
        {
            Rectangle rect = new Rectangle(x, y, w, h);
            Bitmap cropped = bitmap.Clone(rect, bitmap.PixelFormat);
            return cropped;
        }
