EPUB conversion
Word, PDF, Google Doc → retail-grade EPUB. Free.
Upload your manuscript in any common writing format. We produce a clean, validated, WCAG-accessible EPUB that passes every major retailer's check — included on every Chiify plan, with no per-book fee.
Most authors don't want to learn EPUB. They want to write a book and have it appear on Amazon and Apple Books.
But somewhere between Word and the store shelf, your manuscript has to become an EPUB — a specific, fussy format that retailers care about. Done badly, your book has broken navigation or missing accessibility metadata. Done well, it's indistinguishable from a Big-5 publisher release.
Chiify's conversion pipeline was built for institutional publishers who can't ship broken files. We've made it the default for every author at no cost.
What you upload, what we produce
Input
- DOCX — recommended, produces the cleanest output
- Google Doc — export as DOCX first
- Markdown — ideal for technical books
- PDF — works if originally text-based; OCR available for scans
- Plain text — works for poetry, short fiction, simple structures
Output
- EPUB 3.3 with EPUB 2 backward compatibility
- Navigable table of contents linking to every chapter
- Semantic markup — proper headings, paragraphs, lists, blockquotes
- Accessibility metadata for screen readers and EU Accessibility Act compliance
- Passes EPUBCheck 5 and Apple iBooks Asset Guide tests
How the conversion pipeline works
1. Parse and structure
We detect chapters, sections, headings, lists, images, footnotes, and tables from your source file.
2. Build the EPUB skeleton
One XHTML file per chapter, navigation document, OPF package file, and spine.
3. Embed assets
Cover image, interior images, embedded fonts where licensed.
4. Auto-heal any defects
EPUBCheck errors with unambiguous fixes are automatically repaired.
5. Accessibility audit
Final WCAG 2.2 pass — alt-text, language declarations, semantic heading hierarchy.
Lifetime EPUB Warranty
If a retailer ever rejects your EPUB for a technical defect — today, next year, ten years from now — we will regenerate the file at no charge. This warranty has no expiration and no cap.
We'd rather guarantee the file forever than charge you a re-conversion fee every time KDP changes a validation rule.
Frequently asked
Is the conversion really free, or is it a trial?
Really free. Conversion is included on every plan with no per-book fee, no limit on revisions, and no upsell to a premium tier.
Which file formats do you accept as input?
DOCX, Google Doc (as DOCX), Pages (as DOCX), Markdown, plain text, and PDF (with some constraints).
What if my book has images, footnotes, or tables?
Handled automatically. Images are embedded, footnotes become navigable EPUB footnotes, and tables are preserved as semantic tables.
Can I see what the EPUB will look like before publishing?
Yes. After conversion, preview in our in-browser reader or download and load into Apple Books, Calibre, or your Kindle.
What about PDF input?
PDFs from text-based sources convert well. Scanned images require OCR. Complex multi-column layouts may need manual cleanup.
Will my EPUB pass Amazon KDP's strict validation?
Yes. If a retailer ever rejects an EPUB we produced for a technical defect, we fix and re-ship at no charge — our Lifetime EPUB Warranty.
