"Selective JPEG Compression" was a new one for me.
For PNG, always run your images through ImageOptim (http://imageoptim.com http://imageoptim.com) before committing your work.
And for large PNGs, ImageAlpha (http://pngmini.com http://pngmini.com) lets you reduce bit depth, keep transparency and maintain a decent image quality.

- samsolomon 13y agoAnecdotally, I find the best image compression using ImageOptim for PNGs and JPEGmini for JPGs. However, ImageOptim can also compress JPGs.
- xsmasher 13y agoI'm not the OP, but I've had trouble with the JPEGOptim feature of ImageOptim. It created JPEG files that crashed the JPEG decoder on some older android phones. The files worked fine elsewhere, so I think it was an decoder bug not an invalid file, but I had to avoid optimizing JPEG files to avoid the problem. This was about two years ago, so I don't recall version numbers or phone models.
