Convert ODT to EPUB

Why Convert ODT to EPUB?

Converting ODT documents to EPUB transforms your word processor files into professional e-books readable on virtually any e-reader, tablet, or smartphone. EPUB (Electronic Publication) is the open standard for digital books, supported by Kobo, Apple Books, Nook, Google Play Books, and thousands of other apps and devices.

EPUB's key advantage is reflowable content – text automatically adapts to any screen size and reader preferences. Users can adjust font size, margins, and line spacing while the content flows naturally. This makes EPUB ideal for novels, non-fiction books, and any text-heavy content meant for extended reading.

The format automatically generates navigation from your document headings. Each heading becomes a chapter in the table of contents, allowing readers to jump directly to any section. This structured navigation is essential for non-fiction, textbooks, and technical documentation.

For self-publishing authors, EPUB is the gateway to digital bookstores. Apple Books, Kobo Writing Life, and Google Play Books accept EPUB directly. Even Amazon KDP accepts EPUB files, converting them internally to Kindle format. Converting your manuscript from ODT to EPUB is the first step in digital publishing.

Key Benefits of Converting ODT to EPUB:

Frequently Asked Questions (FAQ)

Q: What is EPUB format?

A: EPUB (Electronic Publication) is the open standard for e-books, maintained by W3C. It uses XHTML for content and CSS for styling, packaged in a ZIP container. EPUB files are reflowable, meaning text adapts to screen size and reader preferences.

Q: Will EPUB work on Kindle?

A: Amazon Kindle doesn't read EPUB directly, but Amazon KDP accepts EPUB uploads and converts them automatically. You can also convert EPUB to AZW3/MOBI using Calibre for sideloading. All other major e-readers support EPUB natively.

Q: Which devices support EPUB?

A: EPUB works on Kobo e-readers, Nook (Barnes & Noble), Apple Books (iOS/Mac), Google Play Books (Android/web), PocketBook, Sony readers, and reading apps like Calibre, FBReader, and Aldiko. It's the most universally supported e-book format.

Q: Are images preserved in the conversion?

A: Yes! Images from your ODT document are embedded in the EPUB file. They're optimized for e-readers and work on both e-ink displays (grayscale) and tablets/phones (color). Large images may be resized for performance.

Q: How is the table of contents generated?

A: The converter uses your document headings (Heading 1, Heading 2, etc.) to build the navigation. Each heading becomes a clickable entry in the EPUB's table of contents. Use consistent heading styles in your ODT for best results.

Q: What's the difference between EPUB 2 and EPUB 3?

A: EPUB 2 has maximum compatibility with older devices. EPUB 3 adds HTML5, CSS3, JavaScript, audio/video embedding, and better accessibility. We produce EPUB 2 by default for widest compatibility. Most modern readers support both.

Q: Can I sell the EPUB on bookstores?

A: Yes! EPUB is the standard format for digital publishing. Upload directly to Apple Books, Kobo Writing Life, Google Play Books, Barnes & Noble Press, Smashwords, and aggregators like Draft2Digital. Amazon KDP also accepts EPUB.

Q: How do I edit EPUB files after conversion?

A: Use Sigil (free, open-source), Calibre's built-in editor, or professional tools like Adobe InDesign. Since EPUB is just XHTML in a ZIP, you can also extract and edit with any code editor, then repackage.
