Hi Ahmed,
Conversion to Judaism is a long an complicated process which will often spcan over several years. There is no way to go through this process online, and I suggest that if you really are serious and willing to go through a lot of work, then you should go speak to a local Rabbi. However, as the Rabbi will undouvtedly tell you, there is no need for a gentile to convert to Judaism. Gentiles need not accept the covenant of the Jews in order to go to heaven or be righteous. Regardless, I suggest you go to speak to a local Rabbi to clarify any questions you may have.
