Does it convert AC to DC and vice versa. Please someone explain in clear terms for me, thanks!

A transformer is actually two coils of wire, near to each other but not touching. Each coil surrounds an iron bar but again not touching it. By adjusting the number of turns in each coil you determine the use of the transformer. for instance with 10 turns on the first coil and 20 turns on the second coil you have a 1 to 2 ratio. Consequently if you connected 24 volts AC to the first coil you could expect 48 volts AC out of the second coil. This would be called a step up transformer.
A transformer actually converts any fluctuating voltage. Many say that a transformer only works with AC voltage but they forget the old car radios. In that case they took a pulsing DC voltage and stepped it up for a high voltage for the vacuum tubes.
I hope this helps.

A transformer is a device which transfers energy from one circuit to another via magnetic coupling.

The most common type of transformer consists of two coupled windings with a magnetic core.

Non-ideal transformers can't pass DC - only a changing current.

Transformers don't change DC to AC or AC to DC - often this is confused by calling things "transformers" which actually contain a transformer followed by a rectifier, regulation, and filtering in a wall plug-in brick.

The typical transformer in one of those charging adapters converts 110VAC to something in the neighborhood of 5VAC to 12VAC, depending on the application.

It transfers AC to AC. It will not transfer DC. All DC is blocked by a transformer unless it is a changing DC. Check out the following:

A transformer, like you see on a powerpole, reduces the voltage from, (most often) 4,160 volts to 110/220 volts, which is the voltage we use on an everyday basis in our homes. When you see a group of transformers in a fenced in area with a sign that says DANGER HIGH VOLTAGE that is exactly what it means. The primary side, (input voltage) is normally 26,000 volts and the secondary side, (output voltage), is normally the aforementioned 4,160 volts
