Thank you

I recommend using the tablet profile. The profile is only used when converting books with images in them. It sets the maximum size of images. Any bigger than this will be resized down. For current Kobo models there is no need to do this as the device will resize the image when needed. Plus, if you upgrade to a higher resolution ereader, you will have lost image quality.

I'm not sure what you are doing. Are you saying that converting a comic to epub using calibre gives a different result than Kindle Comic Converter? Or are you converting something the KCC produced? Or something else?

From memory KCC resizes images to match the screen size of the device you said you were using. A calibre conversion might downsize an image according to the profile, but it will not upsize an image. And the formatting of the epub produced by both is different. That could make another difference.

I'm pretty sure that chapter for converted comic books are generated in different ways by KCC and calibre. I can't tell you the differences as I don't really use either.

If we are talking about CBR or CBZ as the source, is there a reason you are not just putting these onto the device? Kobo ereader handle both formats and will allow zooming on the images in the comics. They won't have chapters, but it will remember were you are.

Sorry, I'm not sure what you mean. And I don't use KCC or read comics enough to be sure what is happening. I think I would need to see the source book plus know what options you selected.

If you selected your Kobo device in KCC, it is generating a kepub with the double extension ".kepub.epub". If you add this to the Kobo device, it will be treated as a kepub. But, if you add this book to calibre, it will be treated as an epub as calibre only uses the ".epub". Converting this and sending it to the Kobo device will send it as an epub. My guess is that the alignment is handled differently for the two different formats. But, again, I'd need a good test case.
