An e-book presents a book as digital content you read on a compatible screen; an audiobook delivers book content as spoken-word audio you listen to. The main difference is the mode of access, but editions can also vary: an audiobook may be abridged, and some e-books include audio or synchronized narration.
How e-books and audiobooks differ
| Aspect | E-book | Audiobook |
|---|---|---|
| Experience | Read digital text or other book content on a screen. | Listen to recorded spoken-word content. |
| Typical playback | An e-reader, phone or tablet app, or computer reading program. | An audio-capable device or listening app. |
| What to check | File format, digital rights restrictions, and whether the reading system supports the publication’s features. | Whether the recording is abridged and whether it describes relevant non-text content. |
The formats are not tied to one kind of device. An e-book can work on a dedicated reader, mobile device, or computer, depending on its format and the software. An audiobook needs a compatible way to play audio. Publishers and intermediaries may set format and digital rights management (DRM) constraints, so a file that works in one reading system may not work in another. The EU Publications Office notes that not all e-readers support EPUB. EU Publications Office: Introduction to accessible EPUBs; International ISBN Agency: Guidelines for assignment to e-books.

Accessibility depends on the edition and reading system
E-books can offer adjustable, navigable text
An accessible, reflowable EPUB may allow readers to resize text and change its presentation. Depending on the publication and software, it may also support structured navigation and screen-reader access. These capabilities are not automatic: the content needs appropriate structure, and the reading system must support the relevant features. EU Publications Office: Introduction to accessible EPUBs.

Audiobook narration is not screen-reader access
An audiobook provides recorded narration, which can be a useful listening option, but it does not necessarily provide the navigable text or controls available in an accessible digital publication. WIPO cautions that “The experience of reading with a screen reader is nothing like having a publication read to you, or listening to a recording, and is much closer to reading by sight.” WIPO, Accessible Publishing Best Practice Guidelines for Publishers.
Neither format is accessible for every person or in every edition. Consider the reader’s needs, the structure and features of the publication, the narration, and the capabilities of the device or app.
Can an e-book be listened to?
Sometimes. An enhanced e-book can include audio, and EPUB can support synchronized text and narration when the publisher has implemented that feature. W3C’s 2026 metadata guide describes synchronized full-text playback as a common EPUB media-overlay use; full audio playback can also make listening to the complete publication an alternative to reading. These features are edition-specific, not a guarantee for every e-book. W3C Publishing Community Group: Expressing Accessibility Metadata in the EPUB Package Document 1.0.
An e-book with added audio and a version without it can be different products. A separately produced audiobook is an audio recording intended for listening, not simply a text file being read aloud by a device.

Check the edition before choosing
- For an e-book: Confirm the file format, DRM restrictions, and compatibility with your device or reading app. Check whether it supports the adjustments or accessibility features you need.
- For an audiobook: Check whether it is abridged and whether the narration describes important visual or other non-text content. Audiobooks may be read or performed by one or more voice actors, and may or may not be abridged. Publishing Accessibility Action Group: FAQs.
- If you want both text and narration: Look for an edition that explicitly includes audio or synchronized playback rather than assuming a standard e-book can be listened to.
For a technical definition, IEC 62571:2011 describes a digital audiobook as an audio file or collection of files with primarily spoken-word content, played in a linear or specified order. The standard addresses digital audiobook file structure, usability, playback, and delivery systems. IEC 62571:2011.

Which format should you choose?
- Choose an e-book if you want on-screen text and the particular edition and reading system provide the text controls or navigation you need.
- Choose an audiobook if you prefer recorded spoken-word playback and the recording’s completeness and content suit your needs.
- Choose an edition with synchronized text and narration if you want to switch between reading and listening, and confirm that its app or device supports the feature.
