Using EPUB Reading Order Editor

Arrange the book’s reading sequence while keeping chapter files and nested navigation intact.

  1. Open the supported source files or try the worked example. The original files remain unchanged.
  2. Drag records or use the up/down controls to set the order. Edit the selected page or item in Details & settings.
  3. Use Preview to inspect the staged result. Undo and redo are available for settings and review decisions. Save the review project to continue later.
  4. Open Export to download the task-specific result or a portable review report. Reopen document exports in your normal reader before sharing. Keep the original source files with any saved project.

Example

The worked EPUB has two chapters and a nested navigation entry. Move Make it useful before Start small. The exported spine and top-level contents follow that order while the nested entry stays with its chapter.

Questions & answers

What can this tool do?

Reorders existing spine items and edits their linear flags in EPUB 2/3. Optional navigation sync sorts top-level TOC/NCX groups by chapter order; nested groups, page lists and landmarks are retained. Chapter content, fixed-layout resources and filenames are not rewritten.

Does this upload or overwrite my source files?

Processing is performed in this browser and exports are new downloads. Sources are kept in memory. Review projects contain decisions and source fingerprints, not original source bytes. Public pages retain existing approved ads and optional analytics.

Can I save and reopen the project?

Yes. Save review creates a JSON project. Reopen it with the exact original files; filename and SHA-256 checks prevent applying decisions to different documents. Front matter can reopen without any source files.

What are the limits?

Use up to eight files, 25 MiB each and 80 MiB total. Text imports are limited to 2 MiB. DOCX/EPUB packages are limited to 120 MiB expanded and 5,000 ZIP entries. Exact Word or ebook-reader pagination is not reproduced in the structural preview. Use unsigned, unencrypted source copies.
