Format a book for Kindle without desktop software

Amazon KDP rejects messy heading styles and broken scene breaks. Use this free Kindle book formatter to convert Word/DOCX to a validated EPUB, clean chapter headings and quotes first, then upload the KDP-ready file on kdp.amazon.com before you fight the previewer.

How to use it

  1. Upload your manuscript (Word/DOCX, TXT, Markdown, or EPUB) or paste text with Chapter headings.

  3. Optionally generate or upload a 1600×2560 px Kindle cover (cropped automatically).

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 file and export an EPUBCheck-validated EPUB sized for Kindle Direct Publishing — the format Amazon recommends for ebook manuscripts.

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?

No. Text is processed only to generate your download file and is not saved to a database.

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.
