TOC and chapters
Check whether a PDF can become an EPUB with a usable table of contents.
A readable EPUB needs more than reflowed text. Readers expect chapter navigation, stable headings, and a table of contents that does not point into page headers or random bold lines. The preview helps decide whether the PDF has enough structure to build that navigation.
Direct answer
What this page helps you decide
Use this page when EPUB navigation matters. The preview should show whether the PDF exposes real chapter structure, whether headings can become a table of contents, and whether repeating headers are being mistaken for chapters.
Best fit
Use cases
- Books where chapter titles must become EPUB navigation.
- PDFs with inconsistent headings or scanned title pages.
- Repair workflows that need a TOC plan before full conversion.
Why PDF headings are hard to trust
A PDF may show large bold text visually, but that does not mean the file exposes a semantic heading. Scans make this harder because chapter titles have to be recovered from OCR, page position, font clues, or manual review.
What to inspect in a TOC preview
Check whether obvious chapter titles appear as headings, whether front matter is separated from the body, and whether page headers are not mistaken for navigation. A bad TOC can make a clean-looking EPUB feel unfinished.
When manual chapter repair is worth it
Manual chapter repair is worth it for long books, reference material, textbooks, and anything readers will revisit. For short one-off documents, a simple linear EPUB may be enough if the body text is readable.
Questions
FAQ
Can a PDF table of contents be reused automatically?
Sometimes, but scanned books and inconsistent headings often need review before EPUB navigation is reliable.
Does every EPUB need a table of contents?
Short previews can be readable without one, but full books and reference PDFs should have usable navigation.
What should I fix first if the TOC is wrong?
Fix heading detection and remove repeating page headers before generating the final EPUB navigation.
