Quite some time ago, I tried out ScriptPng (Tex2002ans recommendation on several threads), and it does a nice job. But you have to watch the parameters, as it tends to reduce bit-depth to 4-bit, which would not display properly in some Sony devices due to a Sony bug.

Love your tools! Greatly appreciated!
There is a way to optimize JPG images even more than is done with ePUB Optimizer. That requires using jpegtran with a specific scan order for RGB jpeg and a specific scan order for greyscale jpg. But you have to be careful. Using the wrong scan order will cause your image to be 0 bytes.

If you want to know about this, I can post what you is needed to get that extra bit reduced.
