The most advanced JPEG image compression on mac?

Sometimes i work with JPEG files for my web designs. There are occasions where the PNG format is not suitable..

There are several optimization techniques for the PNG format, but I noticed that for the JPEG format, the possibilities are limited, especially if you work on a Mac.

Probably the most elegant solution so far is the selective compression that allows you to precisely control the compression in specific areas of the images. If you combine then the image with JpegOptim and jpegtran from libjpeg (or use imageOptim) you can reduce even more the filesize.

I am still not satisfied by this options. I don’t want to buy a license for fireworks only because of the selective jpeg, and I wonder if there’s some other image optimization software out there that offers similar features..

On windows you have Jpeg Optimizer..

Is there any tool that you use for your workflows that you can suggest me?

Thank you


  • MozJPEG is a modernized JPEG encoder, probably the best one you can find. I’ve made a basic web interface for it.

  • Guetzli specializes in producing high-quality files with nearly imperceptible distortions. It’s very, very slow though.

  • JPEGmini is pretty good at recompressing JPEGs to the lowest still-good quality.

  • Adept and imgmin try to automatically adjust quality (avoiding unnecessarily-high quality saves a lot).

The last two are best combined with lossless ImageOptim (includes MozJPEG/jpegrescan) for the most efficient JPEG compression I’m aware of.
