That it only allows lossless compression defeats the point. I only got like a ±3% reduction. So I guess we're back to feature requesting. Thanks anyway.

 I ran into this issue today and I found out that you can set conversion profile to your device, then re-convert your library (EPUB to EPUB in my case). Calibre will reduce the size of images for you.
