How do you get a scanned PDF read aloud on iPhone?

If you cannot select the words in a PDF, it is probably a scan: pictures of pages with no text layer, so the iPhone has nothing to read. Open it in TTS Reader, our free iPhone app, and it recognises the text page by page on the iPhone, then reads the document aloud with each word highlighted.

We make TTS Reader. Facts about Apple’s built-in features come from Apple’s support pages and developer videos, checked on 1 November 2026. This page is about a scan that is already a file, such as a PDF from an office scanner or an email attachment. To photograph a paper page with the camera, see scan to speech.

Why does the iPhone not read a scanned PDF?

A PDF can hold two kinds of content: real text, and images. A PDF made from a Word file or a web page contains text, and any reader can speak it. A PDF made by a scanner or copier often contains only an image of each page. The words are visible to you, but to the iPhone they are just pixels.

Apple’s Speak Screen reads text it can find on the screen, so on an image-only page it has nothing to say. In one Apple Community thread from 2019, a person who had scanned a book into a PDF got the message “no speakable content could be found on the screen”. The answers named the cause and the fix: run text recognition (OCR) on the scan first.

So the fix is always text recognition. The real choice is where it happens: inside a reader app, in a separate OCR app, or by hand, one page at a time.

How can you tell whether a PDF has a text layer?

Open the PDF and look for these signs. One of them is usually enough.

What you try	PDF with a text layer	Scan without a text layer
Touch and hold a word	The word is selected, and you can copy it	No word can be selected (but see the Live Text catch below)
Speak Screen (turn it on in Settings → Accessibility → Read & Speak, then swipe down with two fingers from the top)	The page is read aloud	Nothing is read, or a “no speakable content” message appears
Where the file came from	Usually exported from Word, Pages, a browser or a publisher	Often a scanner, a copier or “scan to email”

One catch on recent iPhones: Apple added Live Text to its PDF engine (PDFKit) in 2022, and it recognises text on a scanned page when you interact with it. So in some apps you may be able to select words in a scan even though the file has no text layer. If selection works but Speak Screen stays silent, treat the file as a scan.

In TTS Reader you do not need to check first: if a PDF has no text layer, the app notices and starts recognising it.

How do you listen to a scanned PDF in TTS Reader?

Add the PDF. In TTS Reader, use the Add menu and pick the file from Files. Or open the PDF where it already is, in Files, Mail or Safari, tap Share and choose TTS Reader.
Wait for recognition. If the PDF has no text layer, TTS Reader recognises the text page by page on the iPhone and shows the progress. For a long document this can take a while.
Press Play. The document is then read like any other, with the current word highlighted. Tap any sentence to start there, and set the speed from 0.5× to 3×.
Lock the phone if you like. Playback controls stay on the Lock Screen and in a Live Activity.

Recognition uses on-device text recognition, and the voices run on the iPhone too, so the scan is not uploaded to be read. That matters for the documents people usually scan: contracts, medical letters, bank statements, school forms. The app detects the language of the text and reads 31 languages with its built-in voices.

What if pages are blurry, handwritten or come out wrong?

Clear printed pages give the best result. Very blurry or handwritten pages may not be recognised. Neat handwriting may be recognised in part; messy handwriting usually is not. What helps:

Get a better copy of the file. If the scan came from an office scanner or a colleague, ask for it to be scanned again more sharply. Recognition cannot recover detail the image does not have.
Scan the paper yourself, if you have it. Photograph the problem pages with the camera in TTS Reader instead of using the file; tips for good light and angle are in scan to speech.
Listen with the page in view. The highlight shows which word is being read, so you can spot a misread word, a number or a name, and check it against the original page.
Do not rely on recognised handwriting for anything that matters, such as dosages, amounts or dates. Read those parts yourself or ask someone.

A scan can also have a poor text layer: the scanner ran its own recognition and saved the mistakes in the file. A reader reads the text layer it finds, so you hear those mistakes. If the speech sounds like nonsense on a page that looks fine, this is the likely cause; scanning the paper again with the camera avoids it.

Can you do it with the iPhone’s built-in features for free?

Yes, for a page or two. iPhone has free built-in tools that cover a short scan without installing anything:

Take a screenshot of the PDF page.
Open the screenshot in Photos and tap the Live Text button. Tap Select All, then Copy.
Paste the text into Notes, select it and tap Speak. This needs Speak Selection, which you turn on in Settings → Accessibility → Read & Speak (Spoken Content in earlier versions of iOS).

According to Apple, Live Text needs an iPhone XS, iPhone XR or later with iOS 15 or later, and works in Photos, Camera, Safari, Quick Look and more. It is free and runs on the iPhone. For a one-page letter it is a fine choice, and you do not need our app.

Where it gets tedious: you repeat the screenshot, copy and paste for every page, the text is read in Notes rather than on the page, and nothing keeps your place across pages. For a 30-page contract or a scanned chapter, a reader app that recognises the whole file and keeps your place is less work.

If what you need is a searchable PDF to keep or to send to someone, a dedicated OCR app that saves one is the right tool. TTS Reader is made for listening on the iPhone.

Does this help with dyslexia?

Scanned handouts and forms are often hard to read: small print, grey copies, crooked pages. Hearing the text while each word is highlighted helps many people with dyslexia follow along and keep their place. It is a reading aid, not a treatment. Settings that make listening easier are on text to speech for dyslexia.
