For webtoon creators
Webtoon Creator Kit: Sizes, Slicing, Pacing and a Free Pilot
Quick answer
To start a webtoon, draw at 1,600 px wide and export at 800 px, cut the episode into slices up to 1,280 px tall between panels, pace with space (small gaps for action, long ones before reveals), and plan three episodes before posting. The free webtoon slicer cuts slices as a ZIP, and the webtoon maker can draw a pilot episode from your idea to test it.
The numbers
- Final width: 800 px. Working canvas: 1,600 px wide.
- WEBTOON CANVAS upload images: up to 800 × 1,280 px each, under 2 MB, up to 20 MB per episode.
- Episode length: about 40 to 60 panels.
- Plan three episodes before you post one: readers decide by episode 3.
Test your idea with a pilot
Before you spend weeks drawing, make a rough pilot: type the hook into the webtoon maker, pick romance, action fantasy or slice of life, and it draws an episode of up to 24 panels with the same characters in every one, lettered and sliced to 800 × 1,280 px. Show it to friends or your community and see if they ask for episode 2.
If you post AI-drawn art, check the platform's current rules first and label it honestly.

1,600 px wide for drawing, exported at 800 px wide. Panelo's webtoon maker exports at 800 px wide already sliced.
Is the slicer free?
Yes, with no sign-up. It runs in your browser, so your art isn't uploaded.
