EPUB to audiobook

Convert EPUB to audiobook

Drop in your EPUB. Warblize keeps every chapter, the cover and the metadata, then narrates the whole book with a studio voice.

DRM-free EPUB 2 and 3. Also works with PDF and TXT or DOCX.

What an EPUB gets you

Chapters, exactly as written

Warblize reads the EPUB's table of contents and turns it into real chapter markers, so listeners skip and scrub the way they do in any audiobook player.

Cover and metadata kept

Title, author, description and cover art are written into the M4B and MP3 files. It looks right in Apple Books, Plex and any player.

Narrated, not read out

Emphasis, dialogue and footnotes are handled before a word is spoken. Pick a voice, or cast a different one for each character.

How it works

Three steps from a file on your desktop to an audiobook in your library.

1

Upload your EPUB

Drag it into the composer above. Chapters, cover and metadata are detected on the spot.

2

Pick a language and a voice

47 languages and 30 studio voices. If the language isn't the one the book was written in, Warblize translates as it narrates.

3

Download M4B or MP3

A 60,000-word novel finishes in about 8 minutes. Open the studio while it renders to fix any line.

Stop wrestling with Calibre

The plugin-and-TTS route works, eventually. This one works now.

Calibre + a TTS plugin

  • Two to four hours of setup and conversion
  • Chapter breaks and cover art lost along the way
  • One flat voice for every character
  • No metadata written into the files
  • Breaks on footnotes, tables and images

Warblize

  • Minutes, fully automatic
  • Chapter markers straight from the EPUB
  • Studio voices, with a cast per book
  • Cover, title and author embedded
  • Footnotes, tables and captions handled

The easiest way to convert EPUB to audiobook

Warblize is the modern alternative to Calibre's ebook-to-audiobook workflow. Instead of configuring plugins and putting up with robotic text-to-speech, upload a DRM-free EPUB and get a professional audiobook in minutes.

The parser understands EPUB natively. It reads the navigation document, keeps chapter breaks, extracts the cover and metadata, and deals with the formatting that trips up other tools: italics for emphasis, footnotes, image captions. The result is ready for accessibility, for learning on the go, or for publishing to Spotify, Apple Books and more.

Export MP3 for universal playback or M4B for full chapter support. Narrate in any of 47 languages while keeping the original structure. Novel, textbook or technical manual, Warblize makes your library listenable.

EPUB to audiobook, answered

Does it work with DRM-protected EPUBs?

No. Warblize converts DRM-free EPUBs that you own or have the rights to. EPUB 2 and EPUB 3 are both supported.

Will my chapter breaks be preserved?

Yes. Warblize reads the EPUB's NCX and navigation documents to find the exact chapter structure. M4B downloads carry those chapters into Apple Books and any other player.

Can I narrate an English EPUB in Spanish or another language?

Yes. Pick any of the 47 supported languages. If it differs from the language the book was written in, Warblize translates as it narrates, keeping the chapter structure intact.

What output formats do I get?

MP3 (per chapter or as a single file) and M4B (an audiobook with chapters, cover and metadata). M4B is the better listening experience.

How much does it cost?

Uploading and looking through your book is free. Narration is credit-based: one credit covers 60 minutes of finished audio, and credits stay valid for 12 months. Monthly plans bring the price per credit down.
