I am trying to convert a manga into an e-reader format on my Kindle. Made a zip file with jpegs, import into Calibre, convert to Mobi or AZW3. I get significant margins around the images, they are smaller than they could be on my device, makes the text hard to read. I tried everything I know- played around with output device settings (set it to higher resolution), tried overriding resolution and putting in a custom value, tried clicking "ignore margins" on Mobi output- nothing works! In another converter- Kindle Comics Converter - this problem doesn't exist, it automatically fits the image to screen- but the quality is worse than Calibre (its a problem because I read in Japanese and small quality fluctuations make a big difference in being able to read characters), so I would like to use Calibre's conversions.
I played around with this for hours and cannot find a solution, please help!
