LosslessJpeg increases filesize - If you write a new file usinge the LosslessJpeg.write Methoud the filesize increases

i used the following code. A simple losslessJpeg.Write without changing some settings (IPTC, EXIF, XMP) produces an output file

with increased filesize (from 655 KB to 734 KB).

Why has the filesize significantly changed?

public static void metadataTest()
        {
            using (var losslessJpeg = new LosslessJpeg(@"input.jpg"))
            {
                losslessJpeg.Write(@"output.jpg");
            }
       }
