How to have your iPhone read a PDF aloud

There’s a free way built into iOS, good for a page or two. For a whole report or paper, Luni reads it like an audiobook and remembers where you stopped.

The free way: Speak Screen

Every iPhone can read the screen out loud. It’s off by default.

  1. Open Settings › Accessibility › Spoken Content and turn on Speak Screen.
  2. Open the PDF in Files, Books or Mail.
  3. Swipe down from the top of the screen with two fingers. Your iPhone starts reading, and a small controller lets you pause or change the speed.

The menu names move between iOS versions. If you can’t find it, search Settings for “Speak Screen”.

Where Speak Screen falls short

  • It reads what’s on the screen, so page numbers, running headers and footnotes get read too.
  • It doesn’t remember your place. Stop halfway and you scroll back to find it.
  • It reads one thing. There’s no queue, so it stops at the end of the PDF.
  • The voices are the system ones, and you choose them in Settings.

For a two-page letter, that’s fine. For a 40-page report you want to finish on your commute, it gets in the way.

With Luni: a PDF you listen to like an audiobook

  1. Open the PDF in Files or Mail, tap Share and pick Luni.
  2. Press play. Luni reads it with the voice you picked.

What changes:

  • Only the text you want. Luni skips page numbers, running headers, footnotes, captions and tables, and doesn’t cut a paragraph that runs on to the next page.
  • Your place, saved. Ten minutes on the bus and ten more at lunch add up to a finished report.
  • Lock the phone. It keeps reading in the background and on the lock screen, then moves on to the next thing in Up Next.
  • Your pace. From 0.75× to 2×, with a sleep timer.
  • Works with no signal. The voices run on the iPhone, so a PDF plays on a plane and your file never leaves the phone.
  • No limit. Luni Pro doesn’t count hours or pages.

Questions

Can my iPhone read a PDF aloud for free?

Yes. Turn on Speak Screen in Settings › Accessibility › Spoken Content, open the PDF and swipe down from the top of the screen with two fingers.

What does Luni cost?

Luni is free to download. Listening to your own PDFs needs Luni Pro, a subscription with a 7-day free trial and no listening limit. We’ll publish the price at launch.

Can Luni read a scanned PDF?

Not yet. A scanned page is a picture with no text in it, and Luni needs the text. A PDF you can select text in will work.

Does my PDF get uploaded anywhere?

No. The voices run on your iPhone, so the file and its text stay on it. Once the PDF is in Luni, it plays with no signal.

Can I turn the PDF into an MP3?

Not yet. MP3 export is coming in a later update. For now Luni plays the PDF in the app, with your place saved.

Your reading list, out loud

Luni is coming to iPhone soon. Leave your email and we’ll tell you the day it’s out.

We’ll let you know when it’s available.
