What does Document to Audiobook do?
Document to Audiobook turns e-books, documents and web articles into audiobooks. Give it an EPUB, PDF, DOCX, MOBI, AZW3, ODT, RTF, TXT, PPTX, XLSX, HTML page or any of 176 file types, and you get an MP3 or M4B audiobook with chapters, the book title and author in the tags, and a timed SRT transcript.
- Batch: up to 100 URLs, or one ZIP / 7z / RAR / TAR with any number of documents (up to 200 per run), in the same or different formats. Each document becomes its own audiobook, or all of them become one audiobook with a chapter per document.
- Chapters: taken from the book's headings (EPUB, DOCX, Markdown, HTML ...), the PDF's bookmarks, or lines like "Chapter 3" in plain text. Slides become one chapter each.
- 322 natural neural voices in 75 languages, chosen automatically from the text's language, or the one you name. Speed, pitch and volume are adjustable.
- AI OCR, handwriting included: scanned PDFs, DjVu, photos of pages, handwritten letters and notes, and comic archives are read by an AI vision model that copes with cursive, stains and faded ink. Classic OCR (30 languages) takes over if the AI is unavailable. Handwriting is read best in Latin script; very dense cursive in other scripts (for example Arabic ruq'a) may not be read reliably.
- Web pages: give an article URL and only the main text is read, without menus and ads.
- $0.01 per minute of audio. Failed documents are free.
Who is it for?
- Readers and students: listen to e-books, papers, lecture notes and long articles on the go.
- Publishers and self-published authors: a quick audio edition or a preview of a manuscript, chapter by chapter.
- Accessibility teams: audio versions of reports, policies and handouts for people who prefer to listen.
- Language learners: text and timed SRT side by side, at a slower speed if you like.
- Developers and automations: "document in, audiobook out" over the Apify API, with files you can link to directly.
How to use it
- Upload a file (or a ZIP with many), paste document or web page URLs, or paste text.
- Leave Language on Auto-detect, or pick one; choose a female or male voice, or name a specific voice.
- Pick MP3 (plays everywhere) or M4B (audiobook apps show chapters), then Start.
- Open the Audiobooks tab of the output: each row has a link to the audio file, the SRT file and the chapter list.

The type is recognised from the file name, the server's content type and the file's first bytes, so links without an extension work too. Google Drive, Google Docs, Dropbox and OneDrive share links are turned into downloads (the file must be shared with "anyone with the link"). Password-protected and DRM-protected files cannot be read.
Output
One dataset row per audiobook, plus the files in the run's key-value store (public links in the row).
| Field | Meaning |
|---|---|
status | completed, failed (free) or info (a free note, for example files in a ZIP that are not documents) |
title, author | From the book's metadata, the PDF info, the web page, or the file name |
audioUrl, audioFormat | Link to the MP3 or M4B file |
subtitlesUrl | Link to the SRT transcript (sentence by sentence) |
chapters | {chapterNumber, chapter, start, startSeconds, durationSeconds} for each chapter |
chapterFiles | One audio link per chapter, with "Also save one file per chapter" |
durationSeconds, durationText | Length of the audiobook |
language, voice | The voice that read it (voicesUsed lists more than one if the service dropped a voice during the run) |
characters, words, ocrPages | What was read |
truncated, message | True when only the beginning was read ("Max characters per document" or the run's maximum cost) |
chargedAudioMinutes, chargedOcrPages | What this row cost |
error, message | On failed rows: a short code (download-failed, unsupported-format, protected-document, no-text, speech-failed, BUDGET_LIMIT ...) and a plain explanation |
How much does it cost?
| Event | Price | When |
|---|---|---|
| Audio minute | $0.01 | Per started minute of finished audio. A 10-page article is about 5 to 8 minutes ($0.05 to $0.08); a 300-page novel is about 8 to 10 hours ($5 to $6). |
| OCR page | $0.005 | Per scanned page, photo or handwritten page read with AI OCR. Documents with a text layer never use OCR. |
- Failed documents, unsupported files and info rows are free.
- Faster speech means fewer minutes: at Speed 25% a book costs about 20% less.
- "Max cost per run" is respected: if a document would go over it, only the beginning is read, and the row says so (
truncated). Documents that no longer fit are skipped for free (BUDGET_LIMIT).

Voices
Leave Voice empty to pick one from the language and gender, or name one from this list (the (f) / (m) mark is the voice's gender). With Language: Auto-detect, each document gets a voice in its own language.

Tips
- One file per chapter: turn on "Also save one file per chapter" for players without chapter support, or to share single chapters.
- Many small files into one book: put them in a ZIP (they are read in natural name order: 1, 2, 10) and turn on "Merge into one audiobook".
- Scanned books and handwriting: AI OCR reads any language without settings. OCR language (for example
tur,deu+eng,chi_sim) is used only by the classic OCR fallback. - Technical documents: code blocks are skipped by default; turn on "Read code blocks" to hear them. Tables are read row by row; turn off "Read tables" to skip them.
Limitations
- Files up to 300 MB; up to 200 documents per run; up to 2,000 OCR pages per document.
- Speech is generated by online neural voices (the Microsoft Edge read-aloud voices, through the open-source edge-tts library). The service sometimes stops answering for one voice; the Actor then tries the voice again, then moves to another voice of the same language (
voicesUsed). - Chapter detection depends on the document: a PDF without bookmarks and without "Chapter" lines becomes one long chapter.
- DRM-protected e-books (Kindle KFX, Adobe ADEPT) and password-protected files cannot be read.
- Only convert documents you have the right to use. Audio made from someone else's book is for your own listening unless you hold the rights.
FAQ
Are there extra fees? No: you pay only the per-minute price above (and OCR pages, if any). There is no separate API key or subscription.
Which player shows the chapters? M4B: Apple Books, BookPlayer, Smart AudioBook Player, VLC and most audiobook apps. MP3 chapters (ID3 CHAP) are shown by VLC, Pocket Casts, Overcast, foobar2000 and many podcast players; others simply play the file from start to end.
Can I read a web page? Yes. Put its URL in "Document or web page URLs"; the main article is extracted (like a browser's reader view).
My audiobook has no chapters. The document had no headings, bookmarks or "Chapter" lines. Split it into files and use a ZIP with "Merge into one audiobook", or add headings.
How long does a run take? About 2 to 4 minutes per hour of audio, plus a little for OCR and large Office files.
