Here's a practical guide to getting from Google Docs to a publishable EPUB:
While you're writing — set up formatting correctly
This is the most important step. Google Docs' EPUB export only works well if you use its built-in styles:
- Use Heading 1 for chapter titles, Heading 2 for sub-sections, etc. (not just bold/large text)
- Use Title style for your book title on a title page
- For your Table of Contents: remove page numbers, since page counts shift on different devices and screen sizes — the chapter links will still work
- Keep images simple and well-placed; complex layouts can break in EPUB
Exporting from Google Docs
Go to File → Download → EPUB Publication (.epub) — Google Docs supports this natively. That's it for the basic export.
However, there's a known catch: Google Docs has a hard time saving the table of contents into an EPUB, and the resulting file may not be fully optimized. For a simple book this may be fine; for something more polished, you'll want to validate or reprocess it.
Validate your EPUB
Before uploading anywhere, run your file through the free EPUB Validator at validator.idpf.org. This catches structural errors that will get your book rejected by publishing platforms.
If the export isn't good enough
A few tools can help clean it up:
- Calibre (free desktop app) — can open your exported EPUB, fix metadata (title, author, cover image), and re-export a cleaner file
- Doc Book Maker — a service specifically built to rewrite Google Docs exports into fully compliant EPUB3 files, ready for Kindle Direct Publishing and other platforms
Publishing platforms
Once you have a clean EPUB, the main outlets are:
- Amazon KDP (Kindle Direct Publishing) — largest audience; accepts EPUB
- Apple Books — via the Apple Books Publisher portal
- Google Play Books — via the Google Play Books Partner Center
- Smashwords / Draft2Digital — distribute to many stores at once
One thing to know about Amazon Kindle
Amazon Kindle doesn't natively support EPUB, but it's easy to convert your EPUB to the MOBI format Kindle uses — or you can just upload the EPUB to KDP and they'll handle the conversion for you now.
The biggest takeaway: invest in proper Heading styles from the start — it'll save you a lot of headaches at export time.
