What a chapter heading becomes

The split is the formatter’s own rule, not a sample export. A line that starts with Chapter and a number or roman numeral opens a section. Text before the first of those lines is left out. A file with no such line becomes one section titled Manuscript. Uploads are about 2.5 MB. The file is sent to build the download and is not saved as a book; the export log keeps a sample of up to 12,000 characters.

Tips for fiction authors

  • Use "Chapter 1" style headings so Kindle book formatting builds a correct EPUB table of contents.
  • Amazon KDP recommends EPUB for Kindle eBooks — KDP stopped accepting MOBI uploads; upload the validated EPUB from this formatter.
  • Run quote normalizer, scene break normalizer, and chapter heading formatter before export for cleaner KDP formatting.
  • Print PDF opens styled HTML — use Save as PDF in the browser print dialog for a paperback review copy.
  • The KDP bundle ZIP includes README_KDP.txt with a step-by-step upload checklist for first-time publishers.

Common questions
How do I format a book for Kindle with this tool?

Upload a Word/DOCX, TXT, or Markdown manuscript (or paste chapters), add title and author, then download a validated EPUB to upload on Amazon KDP. Optional cover, print PDF, and a KDP ZIP checklist are included.

Can I convert Word or DOCX to EPUB for KDP?

Yes. Upload a .docx up to about 2.5 MB and export an EPUB, which is the manuscript format KDP accepts. EPUBCheck runs when it is available on the server; otherwise the file gets a structural check. A line that starts with “Chapter” and a number starts a section. Text before the first of those lines is left out of the book. With no chapter line, the file becomes one section titled Manuscript.

Is this a free Kindle Create alternative?

It is a free online Kindle formatter that outputs standard EPUB (and print PDF/DOCX), not Amazon's proprietary KPF. EPUB works for KDP upload and is easier to take wide to other stores.

Is my manuscript stored on Entangled Text servers?

It is uploaded so the server can build the EPUB, PDF, DOCX, or ZIP, and it is not saved as a book project. The export log keeps a sample of the manuscript and of the first chapters, up to 12,000 characters each. A signed-in Save to account stores the form, including pasted text. Files are limited to about 2.5 MB, and exports are capped per network (12 an hour unless that site setting is changed), signed in or not.

What is the difference between EPUB and the KDP bundle?

EPUB is the ebook file you upload as the manuscript. The bundle ZIP also includes metadata.json, blurb.txt, print HTML, cover image, and a Markdown backup.

Does this enroll my book in Kindle Unlimited?

No — you choose KU enrollment when publishing on KDP. This tool formats files KDP accepts.

Can I use this for paperbacks?

Use Print PDF or DOCX for print layout review, then refine margins in Word or a print tool before uploading a print PDF to KDP.
