Try this

    static void Main(string[] args)
    {
        //choose my pictures/temp/file.jpg
        string target = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyPictures), "temp", "file.jpg");
        //encode "test.bmp" to "my pictures/temp/file.jpg"
        EncodeToJPEG("test.bmp", target, 25);
    }

    public static void EncodeToJPEG(string sourceBitmap, string targetfile, long quality)
    {
        if(sourceBitmap == null)
            throw new ArgumentException("sourceBitmap");

        if(File.Exists(targetfile))
            throw new InvalidOperationException("target file already exists");

        var jpegCodec = ImageCodecInfo.GetImageEncoders().FirstOrDefault(x => x.MimeType == "image/jpeg");

        if (jpegCodec == null)
            throw new NotSupportedException();

        var jpegParams = new EncoderParameters(1);
        jpegParams.Param[0] = new EncoderParameter(Encoder.Quality, quality);

        var bitmap = new Bitmap(sourceBitmap);

        var dir = Path.GetDirectoryName(targetfile);
        if (dir != null && !Directory.Exists(dir))
            Directory.CreateDirectory(dir);



        bitmap.Save(targetfile, jpegCodec, jpegParams);
    }
