ComicWave keeps the webtoon image slice set plan, generated panels and lettering as separate stages. You can review the structure before drawing and replace one weak result without discarding accepted work.
Webtoon cutter.
The free webtoon cutter splits a long PNG, JPEG or WebP entirely in your browser. Find low-detail seam suggestions, adjust every cut, resize the output and download numbered PNG, JPEG or WebP slices individually or as one ZIP.

What you get
The selected image stays on the device and is processed by the browser.
Use the current delivery value supplied by your publishing platform.
Review dimensions and boundaries before downloading the output set.
Save each slice with a stable sequence number for easier upload order.
How it works
Select a local PNG, JPEG or WebP that contains the finished vertical episode.
Enter the current slice limit for your destination and review the generated chunk cards.
Check that boundaries do not cut important content, then download the numbered PNGs.
What the webtoon cutter does
Quiet-seam analysis looks for low-detail rows, not named objects. It cannot guarantee that a face or speech bubble is safe, so inspect and adjust every boundary.

Questions
Choose the long image, set the maximum height, run the optional quiet-seam analysis and inspect every boundary. Adjust cuts with the sliders, then download one file or the complete ZIP.
No. The current cutter reads, analyses and slices the image with browser APIs on your device.
The file picker accepts PNG, JPEG and WebP. Export the numbered slices as PNG, JPEG or WebP and choose quality for compressed formats.
It suggests low-detail rows near each planned cut, which often finds cleaner whitespace. It does not recognise speech bubbles or guarantee a safe cut, so inspect and adjust every boundary.
Use the current official requirement for the platform where you will upload. Limits can change, so do not rely on an old preset.
Yes. Review the boundaries, choose the output format and width, then download all numbered slices in one ZIP or save any slice individually.
