JPEG2K supports lossless via a reversible wavelet transform with integral coefficients (which make it reversible, and so lossless). Here is a reference:

Story of my > life.) > Can you point me to any studies to support the claim that JPEG2000 can indeed be indeed non-lossy? I've seen the claims over the years, but nothing to support it (not that I've actively gone looking for the info, as I haven't had the need).
