PDF to Speech
Read PDFs, Word files and e-books aloud with natural AI voices and save an audiobook file.
Free, no uploads, no sign-up. Runs 100% in your browser.
How PDF to Speech works
Text is pulled from the document on your device. The natural voices use Kokoro 82M (Apache-2.0) through kokoro-js in a background thread (about 90 MB, downloaded once). System voices use your browser speech engine for listening only.
Input: PDF, DOCX, EPUB, TXT, MD, HTML, RTF, ODT. Output: WAV, MP3.
How to use PDF to Speech
- Drop a document or paste text.
- Pick a voice and speed.
- Create the audio and download it.
Tips
- WAV is lossless but large; MP3/AAC/OGG are compact for sharing.
- Engines load on first use and are cached afterwards.
PDF to Speech FAQ
- Are my files uploaded?
- No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
- Is it free? Are there limits or watermarks?
- Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
- Does it work offline?
- Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
