I'm trying more and more to get by sans PhotoShop for my personal/freelance work. I do primarily web work these days and don't do enough side gigs to justify keeping up with the Creative Suite beast.
Alas, that does bring to the table some limitations. On OSX I've been enjoying Pixelmator but it has woefully inadequate PNG export support. I can dump it out as a PNG then use one of the many great PNG optimizers like PNGCrusher and can reduce the size fairly well.
Alas, all of the PNG optimizing tools I've found are purely lossless.
Is anyone familiar with a tool (other than PhotoShop) that would offer up some lossy PNG compression options as well like reducing the color pallet, converting 32bit to 24 or 8bit, etc?
Addendum: I'm open to OSX or Windows software. I could even fire up Ubuntu if I had to, I suppose...
Answer
I ended up using ImageOptim:
What it is is a wrapper around several different PNG optimization tools. It comes with OptiPNG, PNGCrush, AdvPNG, PNGout and a few other's you can add-on.
The idea is that it picks the best tool for the particular PNG.
It's not perfect in that it's still mostly automatic, so I can't fine tune more lossy options. Alas, Pixelmator is still woefully lacking in PNG export options so, for now, this is what I'll use.
