Is this what you need:

procedure TForm1.Paste_and_Convert(in_rv: TRichViewEdit);

var

  rv: TRichViewEdit;

  mem: TStringStream;

begin

  mem := TStringStream.Create('');

  try

    rv := TRichViewEdit.Create(nil);

    try

      rv.Visible := False;

      rv.Parent := Form1;

      rv.Style := RVStyle1;

      rv.Options := rv.Options + [rvoAutoCopyRTF];

      rv.PasteRTF;

      rv.SelectAll;

      rv.SaveHTMLToStream(mem, '', 'stream', '', []);

    finally

      rv.free;

    end;

    mem.Position := 0;

    in_rv.InsertText(mem.DataString);

  finally

    mem.Free;

  end

end;

procedure TForm1.Button1Click(Sender: TObject);

begin

  Paste_and_Convert(RichViewEdit1);

end;

Hope it helps.
