Text-to-speech uses voices available on your device
This tool extracts embedded digital text in your browser and uses your system's built-in Web Speech synthesis engine with full playback control.
Your browser speaks the text
Whether proofreading a manuscript to catch awkward phrasing, reviewing reports hands-free, or studying textbook materials, listening provides an efficient alternative to screen reading.
The text layer is parsed locally via pdf.js. Speech synthesis is handled through the standard Web Speech API using native operating system voices. Processing is designed to run in your browser.

What Each Control Does and How to Use It
How each setting interacts with your browser's native text-to-speech engine.
Text Extraction
Extracts the embedded digital text layer from your PDF. Scanned pages containing flat images require OCR before text can be spoken.
Language & Voice
Lists speech synthesis voices installed in your OS and browser. Selecting a language filters the dropdown to matching accents.
Voice Filter
Filters voices based on internal voice descriptors. If filtering yields an empty list on your device, choose "All Voices".
Rate, Pitch & Volume
Adjust playback speed (0.5x to 2.0x), pitch tone, and loudness. Values are passed directly to the speech engine.
Reading Mode
Continuous mode advances automatically across pages. Page-by-page mode pauses after each page so you can proceed at your own pace.
Save Settings
Saves your chosen voice, speed, pitch, and volume to localStorage and restores them automatically on your next visit.
Troubleshooting Common Playback Issues
Quick solutions to common browser and document issues.
No sound when pressing Play
The document is an image-only scan with no text layer.
Extract text using PDF OCR to Text, then paste the text here.
Voice list is empty
No system voice installed for the selected language.
Select another language, set Voice Filter to "All Voices", or install voices in OS settings.
Voice Filter hides voices
Installed voices lack gender indicators in their system names.
Set Voice Filter back to "All Voices" to view all available voices.
Playback stops unexpectedly
Browser engine timeout or pause event.
Click Resume or Stop and restart. The tool automatically splits long text into chunked sentences.
Password-protected PDF fails
Encrypted PDFs cannot be decoded client-side without credentials.
Unlock the PDF before loading it into the reader.
No sound on Play
Cause: Scanned PDF with no digital text.
Fix: Run OCR first, then paste text.
Voice list empty
Cause: No installed voice for that language.
Fix: Select "All Voices" or choose English.
Playback stops
Cause: Browser speech engine timeout.
Fix: Click Resume or restart playback.
Encrypted PDF
Cause: File is password protected.
Fix: Remove password before uploading.
Best Practices for a Smooth Listening Experience

Page-by-Page for Dense Text
Enable page-by-page mode when reviewing technical, financial, or legal documents.
Stop Before Changing Pages

Frequently Asked Questions
Clear answers regarding tool functionality, privacy, and voice compatibility.
Are my PDF files uploaded to a server?
PDF text extraction and speech playback are designed to run directly in your browser. The tool does not intentionally send your document or extracted text to an AllInOneTools processing server.
Does this tool work with scanned PDFs?
This tool reads the digital text layer already embedded in a PDF file. Scanned PDFs with pure images lack selectable text. You can run scanned documents through our PDF OCR to Text tool first, then paste the extracted text here.
Can I choose different voices and languages?
Yes. The tool accesses the speech synthesis voices installed in your operating system and web browser. Language availability and voice naturalness depend on your device configuration.
What does Save Settings store?
Save Settings stores your selected voice, reading speed, pitch, and volume in your browser's localStorage. It does not save the PDF document or its extracted text.
What happens to my document when I close the tab?
Because all processing occurs in local memory, your document and extracted text are immediately cleared as soon as you close or reload the page.
