  JPEG2000: the Killer Image File Format for Lossless Storage
Subject:   PNG?

Response to: PNG?

I did a quick test between PNG and JPEG2000 Lossless. On several of the tests, JPEG2000 did better with files about 3/4 as large as the PNG versions. On the rest, PNG did much, much better with files 1/3 to 1/6 the size of the JPEG2000 files. Based on the few samples I looked at, I suspect that for pictures from a digital camera, JPEG2000 will do better than PNG. However, on a (24bit color) computer made file that PNG easily compressed, JPEG2000 barely managed to compress the file as all.
