Free PDF to Audiobook Converter

How it works

1. Open "More options" under the box, then use Import to load your PDF. The text is read on your device and appears in the box.
2. Pick a voice. If the text is longer than 500 characters, press Generate and it is split into parts. Press "Make" on each part.
3. Press "Join finished parts into one MP3" and download it. Do one MP3 per chapter for an easy audiobook.

How to convert a PDF to an audiobook, step by step

Open "More options (free)" under the text box and find the Import section. Choose your PDF (Word, EPUB, PPTX and TXT files work too). The file is read in your browser, so nothing is uploaded, and the text lands in the box.

Free clips are up to 500 characters each. When you press Generate on a longer text, the tool splits it into 500-character parts. Press "Make" on each part, then "Join finished parts into one MP3". You get one audio file for the whole section, ready to download.

So you can convert a whole PDF to an audio book free, it just takes a few clicks per part. An account or plan lets you make longer parts at once.

Tips for a better audiobook

• Work one chapter at a time. Copy a chapter into the box, make and join its parts, and save it as "01 Chapter one.mp3". Numbered files play in order in any audio app.
• Remove running headers, page numbers and footnotes first. Use find and replace in More options to delete a repeated header line in one go.
• Tick "Join broken lines (PDF copy-paste)" in the clean-up options, so sentences that wrap across lines are read smoothly.
• Add a pause between scenes with [pause 2s], and say the chapter title at the start, such as "Chapter three. The harbour."
• Teach the voice names and made-up words in the pronunciation list, so a character name is said the same way every time.

Scanned PDFs and photos of pages

Import reads the text layer of a PDF. A scanned PDF is just pictures of pages, so it has no text to read. If you cannot select the words in your PDF viewer, that is the reason.

For a few pages, take a photo or screenshot of each page and use "Text from photo" in the Import section. It reads the words from the picture in your browser. Check the text before you generate, because small print and odd fonts can come out wrong.

Which voice works best for an audiobook?

A calm, natural voice is easiest to listen to for a long time. Andrew is preselected. Ava, Emma, Brian and Jenny are also good for AI audiobook narration, and the language menu has British, Australian, Indian and many other voices.

Make the first page in two or three voices and listen on your phone before you start the whole book. If the pace feels fast, lower the Speed slider in More options by 5 to 10 percent.

What it does and does not do

• It reads your text with a standard AI voice and gives you MP3 files. You can change the voice, pitch and speed.
• It does not add music, sound effects or character acting, and it does not clone your own voice.
• It does not make M4B files with chapter markers. Keep one MP3 per chapter instead.
• Only convert books and documents you wrote or have the rights to. If you plan to sell the audiobook on a retail platform, check that platform's own rules on AI narration first.
