The workflow stays reviewable
ComicWave keeps the webtoon canvas plan, generated panels and lettering as separate stages. You can review the structure before drawing and replace one weak result without discarding accepted work.

What you get
Separate working and upload files
Keep one high-quality long canvas and create smaller delivery derivatives from it.
See the exact remainder
The final chunk uses only the pixels left instead of silently padding the episode.
Plan before slicing
Estimate the count and sizes before committing to a production export.
Keep a size note
Download the plan and verify every value against the platform's current upload rules.

Questions
Use a working width and export sizes that match the current rules of your publishing platform. Keep a higher-quality source file so delivery limits do not become the only copy of your art.
Upload rules can change and differ by service or region. The planner accepts custom dimensions so you can enter values from the current official documentation.
The tool divides total height by the maximum chunk height, creates full chunks first and gives the last chunk the exact remaining pixel height.
Yes when possible. A slice should avoid faces, text and important action. This calculator plans dimensions; inspect the real artwork before final cutting.
Yes. The text note includes the full canvas and every numbered chunk dimension.
No art is required. Enter dimensions only. Use the separate webtoon cutter when you want to process a local image in the browser.
