Rectifiers (which convert AC to DC) are quite efficient. Apparently up to 98% [0]
And then there is the voltage conversion, which traditionally happened on the AC side (inexpensive and simple AC transformers are generally why the transmission and distribution systems are AC). Modern power supplies allow for buck/boost on the DC side.

USB-C power supplies are above 90% efficient. [1]
