SpeakCoveThe quickest free way to turn a PDF into an audiobook is to listen to it directly: open the PDF in SpeakCove's free PDF to audio reader and press Play. It reads the text in 10 natural voices and 31 languages, scanned pages included, with no sign-up, no length limit and no upload. It doesn't create an MP3 file; if you need one, a converter that exports MP3 or M4B can, but your PDF goes to its server.
PDFs are everywhere: ebooks, reports, manuals, research papers, recipes. Reading them on a phone screen is tiring, and the old way of making an audiobook from a PDF meant desktop software, cleanup and a long export. On iPhone, the free SpeakCove app keeps the PDF in your library like an audiobook, offline and with your place saved. This guide shows both routes, including for scanned PDFs.
Prerequisites
- A DRM-free PDF on your computer, phone or tablet
- For the web: a current version of Chrome, Edge or Safari
- For iPhone or iPad: SpeakCove from the App Store (free), iOS 26 or later
How to Listen with SpeakCove
1Open the PDF in the free web reader
Go to speakcove.com/pdf-to-speech, choose Open a book or document and pick the PDF. Its pages appear beside the text. When a PDF has no text layer, the pages are recognized in your browser first.
2Choose a voice and speed
Pick one of the 10 voices and a speed from 0.75x to 1.75x: slower for dense technical content, faster for lighter reading. The sentence being read is highlighted, so you can follow along.
3Put it on your iPhone for offline listening
In the browser, reading stops when the iPhone locks. In SpeakCove, tap + and choose Import File, or share the PDF to SpeakCove from Mail, Safari or Files. Text recognition runs on the device with Apple Vision, so scanned PDFs play offline too. Serena and Max are free.
4Jump to the part you need
In the app, scroll to any page and tap a sentence to start reading from there. This lets you skip a table of contents, a preface or a reference list.
5Use the sleep timer for long listening
In the app, set the sleep timer to 5, 10, 15, 30, 45 or 60 minutes when you listen before bed or have a fixed amount of time. Playback stops by itself.
Alternative Methods
iPhone Speak Screen
Turn on Speak Screen in Settings > Accessibility > Read & Speak. Open the PDF in Books or Files and swipe down with two fingers from the top of the screen.
Accessibility Reader (iOS 26)
Open the PDF, then start Accessibility Reader from Control Center or the Accessibility Shortcut to view the text full-screen and listen.
PDF-to-MP3 converters
Converter websites upload your PDF and return an MP3 or M4B file you can play in any audiobook or music app.
Free Text to Speech, Right in Your Browser
Paste text or open any file (PDF, EPUB, Word, scans and more) and press Play. SpeakCove reads it aloud with natural voices in 31 languages. It's free, with no sign-up and no length limit, and your text never leaves your browser.

Frequently Asked Questions
- Can I turn a PDF into an audiobook for free?
- Yes. Open it in SpeakCove's free web reader at speakcove.com/pdf-to-speech and press Play: 10 voices, 31 languages, no sign-up and no length limit, and the PDF stays in your browser. On iPhone, the free SpeakCove app does the same offline, with two voices.
- Can I download the audiobook as an MP3?
- No. SpeakCove reads aloud live, on the web and in the app, and doesn't create audio files. If you need an MP3 or M4B, use a converter that exports audio, and keep in mind that it uploads your PDF to its server.
- Can SpeakCove read any PDF?
- Any DRM-free PDF. Digital PDFs and scanned or photographed pages both work, because SpeakCove recognizes the text on each page on your device. Handwriting and faint copies are less reliable.
- Does it work with large PDFs like textbooks?
- Yes. There is no size limit. Scroll to the page you want and tap a sentence to start there; your place is saved automatically.
- Do I need internet to listen to a PDF?
- Not in the app: once the PDF is imported, text recognition and speech run on your iPhone, so it plays in airplane mode or on the subway. The web reader needs a connection to load the page and download the voices the first time.
- Is my PDF uploaded to a server?
- No. The web reader opens the PDF inside your browser, and the app processes it on your iPhone or iPad with no analytics or tracking. If iCloud sync is on, your library syncs through your own iCloud account.
- How does the voice compare to a professional audiobook?
- SpeakCove's on-device neural voices are clear and comfortable for long listening, but they are not a human narrator. They work with any text, which narrated audiobooks can't.
- Can I listen to a PDF in the background while using other apps?
- Background and lock-screen playback are part of the $14.99 one-time Premium purchase, which also adds 8 voices and CarPlay. In the free version, playback pauses when you leave the app or lock the phone.
