Direct answer
The cleanest way to convert a web serial to EPUB is to start from a readable chapter page, add chapters in order, and use sequence fetching only when the source has obvious next-chapter navigation. If a later page fails, stop there and continue with Manual Entry instead of losing the binder structure.
Sequence fetching works best when
- Each chapter has a standard next link.
- The chapter text is exposed as normal readable HTML.
- The site does not rate-limit the sequence immediately.
When to stop the automated path
Stop if the site returns rate-limit errors, the next page loops incorrectly, or the text extraction becomes unreliable. The URL fetching failure guide covers the recovery path.
