TIFF is probably the safest, but the highest level of JPEG (this is
offered in Photoshop and some other programs) is also a lossless
format and saves a little space. This has come up on various
discussions, and after some research I trust it. Adobe says this is
so, and so do various individuals who work with this daily. But it
still is not as universal as TIFF.
