Can't you just save it as a gif and then make it transparent?

The thing is that gif are limited to 255 colors (8bits: 2^8 = 256 - 1 color for transparency), when png/jpg are more than 4'000'000'000 colors (32bits: 2^32 = 4'294'967'296)
To convert a jpg to gif, you wil need to reduce the available colors in the image, and it can be pretty visible for an image with a shading.
Something else I'd like to add about png, is that's they have a full alpha-blended layer, meaning that you can have 34% opacity, or 67%.
Gif have nothing near that. They define 1 color as being transparent, and that color is either 100% transparent, either 0%.
No smooth blending like in png.
