West Mercia Police said two officers were injured, "but thankfully neither is thought to be seriously hurt".
Three people were arrested for minor public order offences, the force said.
Superintendent Damian Pettit thanked the public for their "co-operation and patience" during the event and said a "small minority of people were more confrontational in their attitude than we wanted".
He added: "Worcester enjoys positive relationships among its diverse communities and we will continue to work with our partners to build on this in the future."
Officers are investigating reports of "items being thrown into the EDL group", he said.
