Compresses photos hard while still looking good, which is why almost every camera and website uses it. It cannot store transparency, and each re-save costs a little quality.

JPEG 2000
A wavelet-based successor to JPEG that holds quality better at small sizes and can carry transparency. It never replaced JPEG on the web, so browser and desktop support is patchy.
