Can transformer convert AC to DC?

No. A transformer cannot convert AC to DC. It can only transform AC power from its primary side to the secondary. However it can step up or step down the primary to secondary voltages. But the output power will always be lesser than input  power in case of an actual transformer.
On the other hand a converter (specifically a rectifier) can convert AC  power to DC power

For the working of the transformer there has to be alternating current, only then an emf is induced and the transformer can step up or step down the voltage.
So it can be said that input given to it is AC and the output obtained is also AC. DC never plays a role in case of transformers.
Hence. Transformers do not convert AC to DC

No bro, we used rectifier to convert ac power in to DC power. And in case of transformer it purely work on ac it can't be work on DC,  if we do so it will be heat dengorously and burn out.

Transformer are use for transforming voltage. Use rectifier to convert AC into dc

Transform is used to step up or step down the AC BUT it is not Possible to convert AC to DC. 

however by using a center tapped step down transformer is used to convert AC TO pulsating DC. 

by connecting filters to it u can get almost DC. 

IN half wave and full wave rectifier transformer used for stepping down the AC not to convert AC TO DC

A transformer changes the level of voltage supplied but it doesn't convert AC to DC. This is achieved by inverters and oscillators.

No transformer cannot convert AC into DC cause we giving an alternating supply to transformer and alternating flux are generate at primary side and this fluxes are traveling through the core comes in secondary side and alternating emf is induced so we can get only AC supply at secondary side.

If we want a DC supply we can use a rectifier converts AC into DC supply at the output of transformer
