Smart Webtoon Cutter FAQ
Production answers without the guesswork
Can the cutter understand panels?+
It detects low-ink rows, not story semantics. Always inspect seams around speech bubbles, effects, and borderless art.
Can I move the suggested cut lines?+
Yes. Enter an exact pixel position for any seam, remove it, or add a new manual seam.
Does the cutter add a watermark?+
No. Numbered outputs contain only the pixels from your source artwork.
