TOC preservation lab
This page is for users who care about navigation quality, not just getting any EPUB file. The tool is paired with guidance for preparing headings so the generated ebook has a better chance of producing a useful TOC.
Best for manuscripts, lessons and long-form guides.
Focuses on chapter labels before visual polish.
Helps diagnose why a TOC feels empty or messy.
preserving chapters formatting and toc
A focused guide plus converter for users who care about table of contents quality as much as the final EPUB file itself.
A DOCX, HTML or similar source with consistent heading levels, meaningful section titles and minimal layout-only decoration.
A cleaner EPUB where chapters, headings and navigation are easier for reading apps to understand.
Source cleanup
A converter can read heading structure, but it cannot reliably infer a clean book outline from random font sizes or blank lines. A little cleanup in the source file often fixes most TOC problems.
Use one title hierarchy throughout the document.
Do not skip from Heading 1 directly to Heading 4.
Remove decorative headers that repeat on every page.
Post-conversion audit
After conversion, open the EPUB navigation panel and ask whether a reader could jump to the right chapter quickly. If not, fix the source headings and convert again.
Look for duplicate chapter names.
Check whether front matter is labeled clearly.
Confirm appendix and bonus sections are reachable.
Before you convert
A quick, practical guide to the file you should upload, the result you will get, what may need cleanup, and which tool to use next.
Use this page when you care about keeping ebook navigation intact, including chapters, formatting and the table of contents. Start with the upload box at the top of the page, then use the notes below to check whether the downloaded file is good enough to keep, share or clean up further.

The converter is already set up for this task. Upload your file, confirm the source and target formats, start the conversion, then download the finished result from the job list.
The converter can only preserve structure that exists in your source file. If the original file is damaged, locked, scanned, or poorly structured, the result may need manual cleanup.
Preservation is poor when the source has fake headings, repeated page headers, broken internal links, missing nav files or images used where real text should exist.
This page explains how chapters, formatting and table of contents survive conversion when the source contains semantic headings, stable reading order and valid metadata.
The converter may run locally for simple text or HTML files, while document and ebook files use the Calibre-backed endpoint for the current job.
Use this page when preservation quality matters most. Use a file-specific page when you already know the exact format to convert.
Open the converted file before you rely on it. A quick reader check usually catches broken chapters, missing images, odd line breaks or metadata problems early.
Do not stop at the download button. Open the result and look for these signs before you share, print, or archive the file.
Realistic examples
Example result for chapters, formatting and TOC
A DOCX manuscript has a title page, ten chapters and subheadings styled consistently throughout the file.
Prepare a manuscript proof with navigable chapters.
Convert course material into an ebook with sections.
Clean up a document before distributing it to readers.
A table of contents cannot be reliably created from visual spacing alone.
Nested headings that skip levels may produce confusing navigation.
Decorative page headers and footers can appear as repeated text if they are part of the source content.
FAQ
Use semantic headings in the source file, keep chapter names consistent and avoid using blank lines as the only divider.
It can normalize many files, but a source with fake headings or broken order may still need cleanup before conversion.
DOCX and HTML usually give better structure than scanned PDFs because they expose headings and text flow more clearly.
After learning preservation rules, manuscript owners often need a DOCX to EPUB page that rewards clean heading styles.
HTML is the next best task when the user wants direct control over headings, links and table of contents generation.
Users who already have a good EPUB may next need a shareable PDF without losing chapter order and formatting cues.
