Free Audiobook Converter — Convert EPUB, PDF, DOCX and TXT to MP3 or M4B. No Sign-Up, No Size Limits, Free Forever.

DocsToAudio has a free Standard tier and a paid Premium tier. Standard is completely free, no account required, no usage limits, no hidden fees — ever. Premium uses ElevenLabs AI voices, which sound more natural and expressive; it requires an account and credits, which can be purchased from your account page.

Standard is free, requires no account, and works great for everyday listening. Premium uses ElevenLabs AI voices, which sound more natural and expressive, offering a wider range of styles, accents, and languages. Premium requires an account and credits.

Credits are used for Premium (ElevenLabs) conversions. The cost depends on the AI model you choose. The estimated credit cost is shown before you start converting. Credits are purchased from your Account page and are valid for 1 year from the purchase date.

You can upload PDF, EPUB, DOCX, and TXT files. Converted audio is available as a ZIP of individual MP3 files (one per chapter) or as a single M4B audiobook with chapter marks.

Not for the Standard tier. You can upload a file and start converting immediately — no sign-up, email, or password needed. An account is required only to access the Premium tier, which uses ElevenLabs AI voices with a credit-based system.

Your original document file is parsed in your browser and is never uploaded to our servers. The selected text of each chapter is sent to our server to generate audio and then forwarded to the relevant speech synthesis provider (Microsoft for Standard, ElevenLabs for Premium). We do not store your documents or generated audio files. See our Privacy Policy for full details.

The Standard tier offers dozens of languages and over 300 voices, including English, Spanish, French, German, Chinese, Japanese, and many more. The Premium tier offers 800+ AI voices in 30+ languages via ElevenLabs, including voices tuned for narration, conversation, education, and more. You can preview any Premium voice before converting.

There is no hard limit, but very large files may slow down your browser. For very long documents, selecting fewer chapters at a time can improve reliability.

No. Conversion runs live in your browser tab — closing or refreshing the page will interrupt it. Keep the tab open until the download completes.

For Standard conversions, refreshing and retrying is always safe and free. For Premium conversions, if a chapter was already processed by ElevenLabs before the failure or cancellation, a small number of credits may have been consumed. You can safely retry; if you experience repeated failures, contact us at support@docstoaudio.online.
