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.

What input and output formats are supported?

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.

Do I need to create an account?

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.

Do you store my files or generated audio?

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.

What languages and voices are supported?

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.

Is there a file size limit?

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.

Can I close the browser tab during conversion?

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

What if conversion fails or gets stuck?

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.

Can I use the converted audio commercially?

Commercial use depends on both your rights to the source text and the terms of the speech service used for conversion. For personal listening, DocsToAudio does not impose additional restrictions. For commercial use — such as selling, publishing, broadcasting, monetizing, or using the audio in public-facing projects — you are responsible for ensuring that you have the necessary rights and that your use complies with applicable laws, platform rules, and relevant third-party speech service terms. DocsToAudio does not guarantee that generated audio is cleared for commercial use.

What is the difference between Standard and Premium?

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.
