What PDF files are supported?

Any PDF with selectable text is supported. Scanned PDFs (image-only) cannot be read aloud since they don't contain extractable text. If your PDF was created from a Word document, web page, or other text source, it will work perfectly.

What is the maximum file size?

The app supports PDF files up to 100MB. For very large files, text extraction may take a few seconds depending on your device's processing power.

Can I change the reading voice?

Yes. The app uses your browser's built-in text-to-speech voices. You can select from all available voices in the Voice dropdown, including different languages and accents.

Why does the voice sound robotic?

Voice quality depends on your operating system and browser. Modern browsers on Windows 11, macOS, and Chrome OS offer natural-sounding voices. For the best experience, use Chrome or Edge with the latest system voices installed.

Can I read a specific page or section?

Yes. Click on any page in the text panel to start reading from that page. You can also use the search feature to find specific content within your PDF.

Does it work on mobile devices?

Yes. The app is fully responsive and works on smartphones and tablets. Speech synthesis is supported on all modern mobile browsers.

Can I adjust the reading speed?

Yes. You can choose from 5 speed presets: 0.75x (slow), 1x (normal), 1.25x, 1.5x, and 2x (fast). Speed changes take effect immediately, even while reading.

Overview

Listen to any PDF using your browser's built-in speech synthesis

PDF Read Aloud extracts the text from any PDF you drop on the page and reads it back to you using your browser's built-in speech synthesis engine — no third-party API, no server processing, and no file ever sent anywhere. Upload a document up to 100 MB, pick a voice from the ones already installed on your operating system, and press Play.

The reader highlights each word as it is spoken and lets you jump to any page or click any word to resume from that exact point. Speed presets from 0.75x to 2x, a volume slider, and a pitch control give you enough flexibility to find a listening pace that works. All text extraction also runs locally using pdfjs, the same open-source library that powers PDF rendering in Firefox.

Frequently asked questions

Is my PDF uploaded to a server when I use this tool?

No. Text is extracted from your PDF entirely inside your browser using pdfjs-dist. The file never leaves your device, and no content is transmitted to any server.

Why can the tool not read my PDF?

PDF Read Aloud requires a PDF with selectable text. Scanned documents that consist entirely of images do not contain machine-readable text, so there is nothing to extract. If your PDF was created by scanning physical pages without OCR, the tool will report that no readable text was found.

Can I change the voice while the document is being read?

Yes. Select a different voice from the dropdown and the reader will stop, apply the new voice, and resume from approximately the same position.

Which browsers support this tool?

Any modern browser that implements the Web Speech API works — this includes recent versions of Chrome, Edge, Safari, and Firefox. Voice quality and availability vary by operating system: Windows 11, macOS, and Chrome OS tend to offer the most natural-sounding voices.
