LINE Webtoons are basically made up of individual image files connected together on their site to look like a one long vertical strip with an upload size of 800px by 1280px
Now I don’t draw my webtoon in that size but I draw my webtoon about triple that canva size so around 1600px by 4600px that way I can zoom in close and avoid that blurry line look while drawing.
When I’m done drawing my webtoon I will draw in a high dpi of 600 but you can draw in a lower dpi like 300 or 72 but be mindful of the blurry effect that might happen.
I then resize the canva size of my webtoon to the upload size of 800px by 1280px either in clip studio paint or using croppy free cropping website.
The reason I save as jpg instead of png is to help keep the file size of each image as small as possible since the maximum upload size can’t be higher than 20MB
If my canva size is still too long then I can also use Krita’s image slicing feature that will cut and resave each image for me. Krita’s image slicing function is similar to the webtoon slicing feature and a great free alternative for Clip Studio Paint.
