Ok basically I use Kindle Comic Converter to make mangas and after this I send them on the kobo having good result as KCC is a very efficient tool. However, I wanted to use Calibre as It's the best way I found to modify metadata and convert epub to kepub (through a plugin). The problem is that whenever I add the ebook to calibre and send it on my kobo clara HD, all the images are shown with really big whitespaces above, under and at the sides. As I said, since I tried to do this without using Calibre achieving the results I was expecting (KCC upscales or stretches the images to the desired lenght and width), I can say for sure that Calibre is the problem. Isn't there a way to just use Calibre to convert and modify metadata without it actually modifying the ebook's content? I hope somebody will be able to help me.
