KOReader is great! The main things comically helps with: * Cropping excess margin (KOReader has this, but Kindles don't) * E-ink screens have way less contrast than regular screens (like 15:1 vs 1000:1), so raw scans often look washed out. Comically increases the contrast to look better on e-ink. * File sizes are huge - why have a 500MB volume when your Kindle only needs ~100MB? Smaller files = faster page turns and way more manga on your device. * Double-page spreads are tiny on portrait screens. Comically can split them up or rotate them so you can actually read them. * If you're processing a bunch of manga at once (I did 72 volumes of Naruto), it's way faster than KCC - like 5 minutes instead of 30+.
