DocsToAudio is completely free. No account required, no usage limits, no hidden fees — ever.

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?

No. Just upload your file and start converting. No sign-up, no email, no password.

Do you store my files or generated audio?

No. Everything runs entirely in your browser. Your documents are never sent to our servers, and no audio is stored on our end.

What languages and voices are supported?

Dozens of languages and over 300 voices are available, including English, Spanish, French, German, Chinese, Japanese, and many more.

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?

Refresh the page and try again. If a large file causes issues, try converting fewer chapters at once. Switching to a desktop browser like Chrome or Edge usually helps.

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.
