Hi.
The problem would be that when I visualize my webtoon/manhwa the quality is reduced too much, at first I thought that the cause of the problem would be the too big resolution of the images that usually are aprox: (1500x10000 ^) Which is strange to me because I always scale my images x2 and reduce the noise with AI to get the best quality possible.

Trying to solve this problem I split the images in 3 parts solving the previous problem but getting a new problem, which would be to have multiple separations in the images in the form of a horizontal division (not in all).

I show both problems in the following images.

what device are you using? there is a limit on how big images can be depending on your device.
