EPUB to audiobook

Convert EPUB to Audiobook (MP3)

Turn an EPUB ebook you have the rights to into a natural-sounding MP3 audiobook — choose Standard or Premium, preview for free, and pay only for your file.

EPUB is the best format you can upload to an audiobook converter. Unlike PDFs, an EPUB stores real text with a real table of contents, so HirayaAI reads your book's actual chapter structure, extracts clean paragraphs and narrates them in order with natural AI voices. The result is a single downloadable MP3 audiobook — not a folder of clips — with proper pauses between sections and ID3 tags your player understands. Premium also includes a chaptered M4B for compatible audiobook players.

Upload your EPUB, choose Standard or Premium narration, and listen to a free preview. The preview is generated from your actual file, so you hear exactly how the finished audiobook will sound before paying anything. You see the exact price after preview. If it sounds right, pay once to convert the whole book.

Good to know

What makes EPUB conversion different

Chapters come from your book, not guesswork. HirayaAI reads the EPUB table of contents first, so chapter boundaries land where the author put them. Books without a usable TOC fall back to heading detection, and junk sections like copyright pages are filtered out of the narration.

DRM-protected files can't be converted. EPUBs locked with DRM (for example, books tied to a store account) can't be read by any converter. HirayaAI is for EPUBs you own the rights to: your own manuscripts, licensed content and public domain books. Kindle formats like AZW or KFX aren't supported — export or convert to EPUB first.

FAQ

EPUB conversion questions

Is converting EPUB to audiobook free?

The audio preview is free with either voice option. Standard is $2.99 per file up to 20,000 words, $6 up to 150,000 words, or $10 for longer files. Premium pricing is calculated from your file during preview. You see the exact price before paying. Applicable taxes are added at checkout. No subscription.

Does the audiobook keep my EPUB's chapters?

Chapters are detected from the EPUB table of contents and narrated in order with pauses between sections. Both options include a continuous MP3. Premium also includes a chaptered M4B for compatible audiobook players.

Can I convert Kindle books or DRM-protected EPUBs?

No. DRM-protected files can't be read, and Kindle formats (AZW, KFX) aren't supported. HirayaAI converts DRM-free EPUB files that you own or have the rights to use.

How long does an EPUB take to convert?
