Why is there such a difference in sizes between the Kindle 1-5 and the Voyage? Shouldn't the file size be smaller when I change the settings, maybe even a quarter of the size like the page on bpc and jpg quality management said?
The Kindle Voyage has more pixels (300 dpi) than the Kindle 1-5 (167 dpi), so each bitmapped page saved by k2pdfopt for the Voyage has a much higher pixel count.
