How Kindle, Apple Books, and Kobo Read Converted EPUBs

This tool outputs a standards-compliant EPUB 3 package with an EPUB2 NCX included for older-reader compatibility. How well that file opens depends on which e-reader app or device you use.

Ready to try the tool this guide describes?

Apple Books and Kobo

Both accept standard EPUB files directly — transferring or opening the generated .epub file works without any extra conversion step.

Kindle

Kindle devices and apps have historically favored Amazon’s own AZW/KFX formats. Direct EPUB support varies by device and app version — some newer Kindle apps accept EPUB directly, while others require Amazon’s "Send to Kindle" conversion step. Check your specific device or app before relying on a direct transfer.

What to expect from the table of contents

Because this tool creates one chapter per original PDF page, the table of contents in your reading app will have one entry per page from the source PDF, not per topic or section.

Why the conversion looks the way it does

See /guides/converting-pdf-to-epub-realistic-expectations for the underlying reasons a fixed-layout PDF becomes a page-per-chapter EPUB rather than a topically-chaptered ebook.

Will the EPUB open directly on my Kindle?

Why does the table of contents have so many entries?
Because the tool creates one chapter per original PDF page, so the table of contents reflects pages, not topics.
Does Kobo support the EPUB2 NCX this tool includes?
Yes — Kobo supports both EPUB3 navigation and the EPUB2 NCX included for broader compatibility.
