Let's separate the JPEG standard from the baseline JPEG file format JFIF (known as JPG or .jpg). The JFIF file-format selects a profile of the JPEG standard also known as baseline JPEG. Baseline JPEG is not lossless. A number of nifty features from the JPEG standard (such as the IBM entropy codec) is left out the baseline format. TIFF (which is not one compression algorithm, but a format supporting several algorithms) supports the full JPEG standard, but this is rarely supported in real life. > gif and png are (normally) lossless compression.

Then we have upcomming JPEG2000. Wavelet compression.
