How to convert a PDF to audio (a beginner's guide)

Ever opened a long PDF document and immediately thought, There’s no way I’m reading all of this?

You’re not alone. Research papers, reports, indie ebooks, whatever it is, long PDFs often feel like a commitment most of us don’t have time for. 

And the problem isn’t necessarily the content, it’s the format. Sitting down and reading dozens of pages on a screen takes focus, time, and a lot more energy than most people have after a long day.

There is hope, though, because text-to-speech (TTS) technology now makes it possible to turn almost any PDF into text-reader audio you can listen to anywhere. That means instead of forcing yourself to read every page, you can simply press play and work through the same document like it’s an episode of a podcast. 

Want to see how this works in real life? Read on for a full breakdown of the simplest ways to convert a PDF to audio, featuring the tools that work best and the step-by-step methods you can use across different devices.

How PDF to audio conversion works

Before we get to the different methods for converting a PDF to audio, it helps to understand the basic technology at play. 

At a basic level, converting a PDF to audio relies on two key technologies: text-to-speech (TTS) and, in some cases, optical character recognition (OCR).

Here’s a quick look at each. 

What is text-to-speech (TTS) 

Text-to-speech (TTS) is the technology that turns written text into spoken audio.

Early versions of TTS were pretty basic. They worked by stitching together small, pre-recorded pieces of speech to form words and sentences. The result technically worked, but it often sounded robotic, choppy, and unnatural. That’s why older digital voices had that unmistakable “computer” sound.

Modern TTS is much different. Today’s systems use neural networks and artificial intelligence (AI) to generate speech that sounds much more natural and human-like. These AI voices can interpret punctuation, pacing, and context, which helps them deliver sentences with a more realistic tone and flow.

The result is audio that’s smooth enough to listen to for long stretches of time (similar to a podcast or audiobook). 

What is optical character recognition (OCR)

Optical character recognition (OCR) is the technology that can read text from images.

This is particularly relevant for PDFs, because many PDFs aren’t actually made of selectable text; they’re essentially pictures of pages (for example, scanned books, printed reports, or photographed documents saved as PDFs).

If you’ve ever tried copying text from a PDF only to get a messy string of symbols or nothing at all, you’ve probably run into one of these image-based files.

OCR solves that problem. It scans the image, detects the letters and words, and converts them into real digital text. Once the text is recognized, other tools (like text-to-speech) can process it and read it aloud.

4 ways to convert PDF to audio 

Now that you’ve got a better understanding of the technology behind it, let’s look at how to actually convert a PDF into audio.

There are several different ways to do it, but not all methods offer the same quality or convenience. Some tools are built specifically for listening and produce natural, human-like voices, while others rely on basic system readers that can sound robotic.

Below are four of the most common ways to convert a PDF to audio. We’ll start with the easiest and highest-quality option, then move through a few alternatives you can use depending on your device and setup.

Method 1: Using a dedicated app (best quality)

This is the easiest way to convert a PDF into audio, and they’re usually the best in terms of sound quality.

Dedicated reader apps (like ElevenReader) are designed specifically for listening, so they come with features you won’t get from basic system readers. For example, things like more natural voices, adjustable playback speed, and smoother navigation through long documents all make a big difference when you’re listening for more than a few minutes.

For this example, we’ll use ElevenReader. It’s a good starting point because the voice quality is excellent and the setup process is super easy: 

• Step 1: Download the app and create an account. Start by downloading the ElevenReader app from Apple’s App Store or the Google Play Store. Once it’s installed, create a free account to get started. The free plan includes a generous monthly limit, which is usually enough to listen to dozens of articles or documents each month.
• Step 2: Import your PDF. Open the app and tap the “+” icon, then choose “From file.” From there, you can browse your device and select the PDF you want to listen to. You can also import content in other ways, like pasting text, adding a URL, or connecting your Google Drive.
• Step 3: Press play. After the PDF is uploaded, it will appear in your library. Tap the file to open it, then hit the play button at the bottom of the screen. The app will start reading the document out loud right away. You can switch voices, adjust the playback speed, and follow along with highlighted text as it’s read.

Other popular apps like Speechify and NaturalReader follow a similar workflow, but ElevenReader’s superior voice quality makes it our top recommendation for this method.

Method 2: Using your browser (no download needed)

If you want a quick solution without installing any new software, you can use your web browser’s built-in reading feature. 

This is a great option for listening to a single document on your desktop.

For Microsoft Edge:

1. Open the PDF file directly in your Microsoft Edge browser.
2. Right-click anywhere on the document.
3. Select “Read aloud” from the context menu.
4. Use the toolbar at the top of the page to play, pause, and change the voice and speed.

For Safari (iOS 17 and later):

1. Open the PDF in your Safari browser.
2. Tap the “aA” icon in the address bar.
3. Select “Listen to Page” from the dropdown menu.

While convenient, the voice quality of browser-based readers is a significant step down from dedicated AI reader apps, and you cannot save your progress or create a library.

Pro Tip: If you prefer listening directly in your browser but want better voice quality, try the ElevenReader Chrome extension. It lets you open PDFs or web pages and listen with the same high-quality AI voices used in the mobile app. 

Method 3: Using Adobe Reader (desktop)

If you already have Adobe Acrobat Reader installed, you can use its built-in “Read Out Loud” feature. This is a very basic tool that uses your operating system’s default TTS voice.

Here’s what to do: 

1. Open your PDF in Adobe Acrobat Reader.
2. Go to the “View” menu at the top of the screen.
3. Hover over “Read Out Loud” and select “Activate Read Out Loud.”
4. To start listening, go back to the same menu and select “Read This Page Only” or “Read To End of Document.”

The voice quality is typically very robotic, making it unsuitable for long documents, but it’s still a functional option if you are in a pinch.

Method 4: Using Google Docs (free workaround)

This method is a useful workaround if you don’t have a dedicated TTS app and want to listen to a PDF on your desktop. It involves converting the PDF to a Google Doc and then using your browser’s accessibility features.

1. Upload the PDF to your Google Drive.
2. Right-click on the PDF file and select “Open with > Google Docs.” This will automatically convert the PDF into an editable Google Doc, preserving most of the formatting.
3. Once the document is open, you will need a screen reader extension for your browser. The official “Screen Reader” extension for Chrome works well.
4. Activate the extension, and it will begin reading the text of the document aloud.

This is a clunky, multi-step process, and the voice quality is poor. However, it is a completely free method that works for any PDF that can be converted to a Google Doc.

Common PDF to audio conversion problems (and how to fix them)

Even with the best tools, you may occasionally run into issues when converting a PDF to audio. Here are the most common problems and how to resolve them.

The app reads garbled or nonsensical text 

This usually happens with scanned PDFs where the OCR has misread certain characters, or with PDFs that have unusual formatting like multi-column layouts or footnotes. The best fix is to use a dedicated app with strong OCR, like ElevenReader, which handles complex layouts more reliably than basic tools. If the problem persists, try copying the text from the PDF and pasting it directly into the app.

The app skips large sections of the document 

This often occurs with PDFs that contain a lot of images, charts, or tables. TTS apps can only read text, so any content embedded as an image will be skipped. If the missing content is critical, you will need to manually transcribe it or find a text-based version of the document.

The voice mispronounces technical terms or proper nouns 

This is a common limitation of TTS technology, particularly with highly specialised vocabulary. Most dedicated apps allow you to adjust the pronunciation of specific words in the settings. Alternatively, choosing a different voice can sometimes improve pronunciation accuracy, as different AI models handle unusual words in different ways.

The PDF is password-protected 

If a PDF is protected with a password, you will need to enter the password before the app can read it. If you do not have the password, you will not be able to convert the document to audio. Some PDFs are also protected against copying and printing, which can prevent TTS apps from accessing the text.

The audio cuts out, or the app crashes on long documents 

Very long PDFs, such as full-length books or lengthy reports, can sometimes cause performance issues in less robust apps. If this happens, try splitting the PDF into smaller sections before importing it. Most dedicated apps like ElevenReader are optimised for long-form content and handle large files reliably, but older or less well-maintained apps may struggle.

Rethinking the way you “read” long PDFs

Long PDFs aren’t going anywhere anytime soon. But that doesn’t mean you have to read every page the traditional way. 

With modern text-to-speech tools, turning a PDF into audio takes just a few clicks. Once it’s converted, you can listen while commuting, walking, working out, or doing chores, making it much easier to get through long documents without staring at a screen.

To quickly recap this article, here are the four main ways you can convert a PDF into audio:

• Dedicated reader apps (like ElevenReader): The easiest and highest-quality option, with natural voices, playback controls, and the ability to build a listening library.
• Browser read-aloud features: A quick, no-download solution for listening to a PDF directly in browsers like Microsoft Edge or Safari.
• Adobe Acrobat Reader: A basic desktop option for Adobe users. 
• Google Docs workaround: A free workaround where you convert the PDF into a Google Doc, and then use a screen reader extension to listen.

So the next time you open a massive PDF and feel that familiar wave of dread, remember: you’ve got options, and finishing it might just be easier than you think.  

Frequently asked questions about converting PDFs to audio 

Can I convert a scanned PDF to audio?

Yes, but you will need a tool with optical character recognition (OCR) technology. Dedicated apps like ElevenReader and Speechify can automatically scan and read these files, but most built-in tools can’t.

Can I save the audio as an MP3 file?

Some desktop applications and online converters allow you to download the audio as an MP3 file. However, most mobile apps are designed for streaming and listening within the app to enable features like text highlighting and progress syncing.

What is the best free way to convert a PDF to audio?

If you’re looking for a free option, the easiest way to convert a PDF to audio is by using a browser’s built-in read-aloud feature or a free plan from a dedicated text-to-speech app.

That said, free plans from apps like ElevenReader often provide a much better experience. They typically include more natural-sounding voices, playback controls, and the ability to save your documents so you can come back and continue listening later.

How does PDF to audio work with different languages?

High-quality TTS apps like ElevenReader support a wide range of languages and accents. When you import a document, the app will often auto-detect the language, or you can manually select the correct voice for proper pronunciation.
