Matthew's gospel says that John's baptism was for repentance but Jesus would baptize in Holy Spirit and fire:
Matthew 3:11 "I baptize you with water for repentance. But after me comes one who is more powerful than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire.
Since Christ had not yet ascended to the Father the Spirit had not yet been given:
NIV John 16:7 But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you.
The unnamed Jew that was disputing about ceremonial washing was under the impression that Jesus was baptizing but John says later that only his disciples did:
NIV John 4: 1Now Jesus learned that the Pharisees had heard that he was gaining and baptizing more disciples than John— 2although in fact it was not Jesus who baptized, but his disciples. 3So he left Judea and went back once more to Galilee.
So was the baptism that Jesus' disciples were doing for repentance also?
NIV John 3: 22After this, Jesus and his disciples went out into the Judean countryside, where he spent some time with them, and baptized. 23Now John also was baptizing at Aenon near Salim, because there was plenty of water, and people were coming and being baptized. 24(This was before John was put in prison.) 25An argument developed between some of John’s disciples and a certain Jew over the matter of ceremonial washing. 26They came to John and said to him, “Rabbi, that man who was with you on the other side of the Jordan—the one you testified about—look, he is baptizing, and everyone is going to him.”
27To this John replied, “A person can receive only what is given them from heaven. 28You yourselves can testify that I said, ‘I am not the Messiah but am sent ahead of him.’ 29The bride belongs to the bridegroom. The friend who attends the bridegroom waits and listens for him, and is full of joy when he hears the bridegroom’s voice. That joy is mine, and it is now complete. 30He must become greater; I must become less.”h
31The one who comes from above is above all; the one who is from the earth belongs to the earth, and speaks as one from the earth. The one who comes from heaven is above all. 32He testifies to what he has seen and heard, but no one accepts his testimony. 33Whoever has accepted it has certified that God is truthful. 34For the one whom God has sent speaks the words of God, for Godi gives the Spirit without limit. 35The Father loves the Son and has placed everything in his hands. 36Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on them.
