Can I listen to a PDF for free?

Yes. Both iOS and Android will read a PDF aloud with their built-in accessibility voices at no cost. The voice is robotic and it reads page furniture like headers and footnotes, but it works offline and costs nothing.

What is the best way to listen to a scanned PDF?

A scanned PDF is images, not text, so a screen reader finds nothing to read. You need a tool that runs OCR first. Most AI narration services do this automatically.

How to listen to a PDF

The fastest way to listen to a PDF is your phone’s built-in screen reader — no app, no account, about thirty seconds to set up. It is also the worst-sounding option, and for a long document that matters more than you would think. Below are the four real choices and what each is genuinely good for.

1. Your phone’s screen reader (free, instant, robotic)

On iPhone, turn on Spoken Content in Accessibility settings and swipe down with two fingers. On Android, Select to Speak does the same job. Open the PDF, trigger it, and it reads.

This is the right answer for a two-page document you need to get through now. It is the wrong answer for a book, because it reads everything — running headers, page numbers, footnote markers, the copyright page — in a flat voice with no idea what a heading is.

2. A text-to-speech app (better voices, still literal)

Dedicated apps use higher-quality voices and let you set speed and skip around. The reading is still literal: it starts at the first character and stops at the last, including tables and citations that make no sense read aloud.

Good for well-structured documents you want to hear in full, unedited.

3. AI narration (a summary or a reading, in a real voice)

Newer tools run the document through a language model first, so they can skip the furniture, read the structure properly, and — if you want — give you a five-minute summary instead of a fifty-minute reading. Scanned PDFs work here too, because OCR happens automatically.

This is what The Path does, and we will be openly biased about it: you save a PDF, and get back something you can listen to on a walk. If you want the full text read instead of a summary, you can have that too.

4. Convert to an audio file

If you want an MP3 to keep — offline, in a podcast app, on a device with no browser — a conversion tool will produce one. Slower and more manual, but the file is yours.

Which to pick

Two pages, right now: the screen reader. Nothing beats already having it.
A long report you must hear in full: a text-to-speech app.
A stack of things you will never find time to read: AI narration.
A file to keep: convert to MP3.

If the honest answer for your document is the free screen reader, use the free screen reader. It is genuinely fine for short things, and we would rather tell you that than waste the thirty seconds it would take you to find out.
