Why Metadata Matters for Your EPUB Conversion
When you convert a Word document to EPUB, most people focus on formatting — fonts, spacing, chapter breaks. But metadata is the invisible foundation that makes your ebook discoverable, professional, and compatible with every retailer from Amazon to Apple Books.
Metadata is the structured information about your book: title, author name, publication date, ISBN, language, copyright holder, and more. It lives in the file properties and appears in ebook readers, store listings, and library catalogs. Poor metadata doesn't just look unprofessional — it can cause your ebook to be rejected by distributors, appear with the wrong author name, or fail to display properly on certain devices.
The good news? You can prepare most of your metadata in Word before conversion, which saves time and ensures consistency across EPUB, PDF, and print formats.
Essential Metadata Fields to Add in Word
Not every metadata field needs to live in Word — some are added during conversion or upload to retailers. But these core fields should be set up in your manuscript before you convert to EPUB:
- Title — The full, exact title of your book (not a working title).
- Author — Your name as you want it to appear everywhere (e.g., "Jane Smith" vs. "Jane Elizabeth Smith").
- Copyright Year — The publication year (usually the current year for self-published work).
- Publisher — Your publishing imprint or name (if applicable).
- ISBN (optional but recommended) — A 13-digit ISBN if you've purchased one for your print edition.
- Language — Set to the correct language code (e.g., English, Spanish, French) so readers and retailers know what they're getting.
- Subject/Keywords — Categories or genres (fiction, memoir, business, romance, etc.).
- Description/Summary — A short blurb about the book (optional in Word, but useful to have drafted).
How to Add Metadata in Microsoft Word
Microsoft Word stores metadata in the file properties, which are read during EPUB conversion. Here's how to fill them in:
On Windows:
- Open your manuscript in Word.
- Click File in the top-left menu.
- Select Info (left sidebar).
- Look for Properties on the right side; click Show All Properties if you see a collapsed view.
- Fill in the visible fields:
- Title — Your book's exact title.
- Subject — Genre or category (e.g., "Science Fiction", "Self-Help").
- Keywords — Comma-separated terms (e.g., "dystopian, future, AI, thriller").
- Category — Broader classification if needed.
- Author — Your name as it should appear in the ebook.
- Manager — Leave blank unless you have a publisher managing rights.
- Company — Your publishing imprint or leave blank.
- Comments — A brief description or blurb (optional).
- Close the Info panel. Word auto-saves these properties.
On Mac:
- Open your manuscript.
- Click File in the menu bar.
- Select Properties (or Document Properties in some versions).
- Fill in the same fields as above in the dialog that opens.
- Click OK to save.
Alternative: Using the Advanced Properties Dialog
For more granular control, you can access the full properties sheet:
- Windows: File → Info → Properties (dropdown) → Advanced Properties.
- Mac: File → Properties → Custom tab (if available).
This dialog lets you add custom fields (e.g., "Publisher ISBN", "Imprint Name") that some EPUB converters recognize.
Copyright and Legal Metadata
Your copyright page (usually the back of the title page in print, or early front matter in ebooks) should state ownership and publication year. But the metadata fields in Word should mirror this information:
- Set the Author field to the copyright holder (usually you, the author, unless you've assigned rights).
- Include the copyright year in the Comments or Description field if Word doesn't have a dedicated copyright-year property.
- If you have an ISBN, note it in Keywords or Comments so it's preserved during conversion.
When you later convert to EPUB, this metadata will flow into the ebook's internal metadata structure, making it legally and technically sound.
Language Settings: A Critical Detail
Many authors overlook this, but setting the correct language in Word is essential for EPUB conversion and retailer compliance.
Why it matters:
- EPUB readers use language metadata to apply the correct hyphenation, spell-check, and text-to-speech rules.
- Retailers filter ebooks by language; if your metadata says "French" but your book is in English, it may be hidden from English-speaking customers.
- Accessibility tools (screen readers) rely on language tags to pronounce words correctly.
How to set it in Word:
- Select all text (Ctrl+A or Cmd+A).
- Go to Review tab → Language (or Tools → Language on Mac).
- Choose Set Proofing Language.
- Select the correct language (e.g., "English (United States)") and click OK.
If your book contains passages in another language (e.g., a French quote in an English novel), select just those words and set their language separately. This ensures proper rendering in the final EPUB.
Front Matter and Metadata Coordination
Your Word document's front matter (title page, copyright page, dedication, etc.) and the metadata fields should be consistent. Here's a checklist:
- Title in Word metadata = Title on your title page.
- Author in Word metadata = Author name on title page and copyright page.
- Copyright year in metadata = Copyright year on copyright page.
- ISBN in metadata (if applicable) = ISBN on copyright page or back cover.
- Language in metadata = Language of the book content.
When you convert Word to EPUB, the conversion tool reads both the metadata and the visible text. Mismatches can cause confusion or errors in the final ebook.
Preparing for Conversion: A Step-by-Step Workflow
Here's how to ensure your metadata is conversion-ready:
- Finalize your title and author name. Decide exactly how your name should appear (first and last only, or middle initial?). This is harder to change after publication.
- Add all metadata to Word properties (as described above).
- Create a copyright page in your front matter that mirrors the metadata (title, author, year, ISBN if applicable).
- Set the document language to match your book's content.
- Review your front matter structure. Ensure your title, copyright page, and any other front matter are clearly marked as chapters or sections so the conversion tool recognizes them.
- Save your Word file (DOCX format) and back it up.
- Upload to your conversion tool (like ebookconvert.pro) and review the detected structure before generating outputs.
Common Metadata Mistakes to Avoid
Typos in author name: Double-check spelling. Retailers index by author name, and a typo will split your books across multiple author profiles.
Inconsistent title capitalization: Decide on title case ("The Great Adventure") or sentence case ("The great adventure") and apply it consistently in metadata and front matter.
Missing or wrong ISBN: If you've purchased an ISBN for your print edition, don't use it for your ebook unless you have a separate ISBN for the ebook version. Most retailers assign their own ebook ISBNs anyway.
Vague or missing keywords: "Book", "Story", and "Novel" are too generic. Use specific terms: "paranormal romance", "sustainable farming", "cyberpunk", etc. These help readers find your work.
Wrong language setting: This is a silent killer. Your ebook may render perfectly on your device but fail spell-check or text-to-speech on others if the language is mismatched.
What Happens to Your Metadata During Conversion
When you upload your Word file to convert to EPUB, the conversion process extracts your metadata from the file properties and embeds it into the EPUB's internal XML structure (called the OPF file). This ensures:
- Your title, author, and publication date appear in ebook readers.
- Retailers can index and categorize your book correctly.
- Library systems and discovery platforms can catalog your ebook properly.
- Your ebook remains legally attributed to you as the copyright holder.
If you later need to update metadata (e.g., you want to change your author name or add an ISBN), you'd typically regenerate the EPUB rather than edit the Word file and reconvert. That's why getting it right in Word, before conversion, saves effort down the road.
Metadata for Print Covers and PDFs
If you're also generating a print-ready PDF or AI cover art, the metadata matters here too:
- Title: Used on the cover and spine.
- Author: Appears on the cover and copyright page of the PDF interior.
- ISBN (print edition): Displayed as a barcode on the back cover.
When you upload your Word file to a tool like ebookconvert.pro, the metadata you've embedded will flow into all outputs — EPUB, PDF, and cover generation — ensuring a cohesive, professional result across all formats.
Final Checklist Before Converting Word to EPUB
- ☐ Title is finalized and spelled correctly in Word metadata.
- ☐ Author name is exactly as you want it to appear everywhere.
- ☐ Copyright year is set (current year for new publications).
- ☐ Language is set to the correct language of your book.
- ☐ Keywords or subject tags are relevant and specific (not generic).
- ☐ Front matter (title page, copyright page) mirrors the metadata.
- ☐ ISBN is noted in metadata if applicable (print edition).
- ☐ Document is saved as DOCX and backed up.
- ☐ You've proofread everything one last time.
Conclusion: Metadata Is Part of Professional Publishing
Converting Word to EPUB isn't just about making text readable on a phone or tablet — it's about creating a professional, discoverable, legally sound ebook. Metadata is the backbone of that professionalism. By taking time to optimize your metadata in Word before conversion, you ensure that your ebook appears correctly across every retailer, reader device, and library system.
The effort is minimal — filling in a few fields in Word properties takes minutes — but the payoff is significant. Your readers will find your book more easily, it will display correctly on their devices, and you'll avoid the frustration of having to regenerate files because of metadata errors. Whether you're using a specialized tool to convert Word to EPUB or handling the process yourself, clean metadata in Word is the foundation of a professional result.
