Image optimization tools?

Question

I'm trying to do research on finding a good jpeg and gif optimizer for linux command but the ones I'm finding date back to 2001 which may be good but it's hard to believe there have been no advanced in the last 8 years.

Do you know of any good performing jpeg and gif optimizers?

Answer 1

Just because it's old doesn't mean it's not any good. ;) Not much has changed with image formats over the past few years either. Have you checked out ImageMagick?
