PNG is lossless by default, as far as I know. The only reason not to prefer it over SGI format that I'm aware of is that FG 1.0 can't deal with it - aside from that, it is much smaller (generally 1/2 to 1/3rd size, in my tests here) and supported my far more software. PNG *can* be lossy, and for all I know the default settings in some tools may even save it lossily, but most PNGs are lossless. It's basically RLE + zlib + some other tricks.
