Yep. PNG has a transparent "color" that allows this.
Here is a better explanation as mine is very rudimentary. 
Transparency of image
PNG offers a variety of transparency options. With truecolor and greyscale images either a single pixel value can be declared as transparent or an alpha channel can be added. For paletted images, alpha values can be added to palette entries. The number of such values stored may be less than the total number of palette entries, in which case the remaining entries are considered fully opaque.
The scanning of pixel values for binary transparency is supposed to be performed before any color reduction to avoid pixels becoming unintentionally transparent. This is most likely to pose an issue for systems that can decode 16 bits per channel images (as they must be compliant with the specification) but only output at 8 bits per channel (the norm for all but the highest end systems).
