How to split a webtoon image
1. Add the finished long canvas
Choose the exported JPG, PNG, or WebP page. The artwork remains on your device; the tool reads it inside the browser.
2. Enter the destination limits
Set one target width and the maximum height allowed for each upload image. Publisher requirements can change, so confirm the current limits on the platform upload screen.
3. Review the cut positions
The preview starts with evenly spaced cut lines. Drag a pink line away from speech balloons, faces, panel borders, and the center of important action. Keyboard users can focus a line and adjust it with the arrow keys.
4. Download in reading order
Files are named with 001, 002, and later numbers. Download them individually or as a ZIP, then upload them in the same order.
