Utility to compress jpeg as good as photoshop or better

Question

Photoshop has a very good jpeg compression algorithm, using which it creates smaller files with same visual quality (compared to for example ImageMagick). Is there some utility, which can produce same or better quality to size ratio?

Answer 1

ImageMagick can get close--it just requires a lot of tweaking. Adobe has proprietary methods for JPEG optimization and they happen to be very good.

• ImageMagick JPEG convert options
