Want to read a PDF aloud without staring at a screen? From built-in OS tools to dedicated apps, here are the best text-to-speech options for PDFs on any device — most of them free.
Frequently Asked Questions
Can I read a PDF aloud for free?
Yes. Adobe Acrobat Reader, Microsoft Edge, macOS Preview, and iOS Spoken Content all read PDFs aloud at no cost. Several free web tools like TTSReader also work without a subscription.
Can text-to-speech read a scanned PDF aloud?
Only if the tool includes OCR. Standard TTS engines read text layers — they cannot read image-based (scanned) PDFs. Tools like Speechify and Natural Reader include OCR to handle scanned documents. You can also [make a PDF searchable](/blog/make-pdf-searchable/) first, then use any TTS tool.
What is the best app to read PDFs aloud?
For free built-in options, Microsoft Edge and Adobe Acrobat Reader work well. For premium voice quality and mobile use, Speechify (55M+ users) and Natural Reader are the top picks. Both support PDFs, OCR, and multiple languages.
How do I listen to a PDF on my iPhone?
Go to Settings > Accessibility > Spoken Content and enable Speech Selection or Speak Screen. Open your PDF in any app, select text and tap Speak, or swipe two fingers down from the top to read the whole screen.
Does reading PDFs aloud help with comprehension?
Yes. Multi-modal learning — reading and listening simultaneously — is shown to improve retention. It also helps people with dyslexia, ADHD, or visual impairments process written content more effectively.
