png-32supports different levels of transparency. Each pixel can have an opacity between 0 and 255, with 0 as completely transparent.png-24supports setting one color as fully transparent. Everything else will be opaque.gifuses a color palette. You can specify that one color in the palette is fully transparent.png-8also uses a color palette but each color in the palette has its own opacity value, so it supports varying levels of transparency too.jpgdoes not support transparency.
