About this tool

Inconsistent scene breaks confuse ebook conversion. This scene break standardizer finds varied dividers — asterisks, dashes, blank lines, hash marks — and normalizes them to your chosen marker (default ***).

Export formatting before KDP upload

Kindle and print workflows punish inconsistent quotes, scene breaks, and chapter headings. Normalize formatting after content edits are done—otherwise you will re-export three times. These transformers run locally; nothing is uploaded.

Tips for fiction authors

  • The three-asterisk (***) break is the most common in manuscript submissions. Use it unless your publisher specifies otherwise.
  • EPUB and MOBI formatters rely on consistent markers to insert decorative scene breaks. Inconsistent markers cause blank gaps.
  • Some AI tools insert random blank lines or hash lines between scenes. Normalizing before formatting saves hours of manual cleanup.
  • Count your scene breaks after normalizing. Too many breaks in a short chapter can fragment pacing — consider merging scenes.
