PDF.js extracts document text in your browser tab. The speech engine is provided by your browser or operating system, so review your device voice and privacy settings when working with sensitive documents.
PDF.js reads the selected file in this browser tab and extracts selectable text for the reader. The page loads its PDF libraries from public CDNs, so an internet connection is needed to load the tool.
The tool does not send the selected PDF to a PDF-processing upload endpoint. The document is held in browser memory while it is being read; close or refresh the tab when you have finished.
The Web Speech API uses voices supplied by your browser or operating system. Some devices may use network-provided voices, so voice processing privacy depends on your device and selected voice.
Built for professionals, students, and businesses who require private, reliable in-browser document processing without server dependencies.
Everything you need to know about technical execution, page formatting, structural integrity, and best practices.
Extract selectable text, then read it aloud
PDF.js reads the text layer stored in a PDF. The reader divides extracted text into sentences and sends each sentence to the browser’s Web Speech API. The active sentence is highlighted during playback.
A simple workflow for books, notes, and reports
Why some pages cannot be read yet
A text-based PDF contains selectable characters that PDF.js can extract. A scanned PDF often contains only page images, so there may be no text for the voice reader to speak.
If a scanned document produces an empty page, use an OCR PDF tool first. Upload the searchable result after OCR has added a text layer. OCR accuracy depends on image quality, language, and page layout.
Available options depend on your device
The voice menu lists voices exposed by your browser and operating system. Some devices offer more languages and accents than others. Reading speed and pitch are passed to the speech engine, but sound and voice quality are controlled by the selected system voice.
For best results, choose a voice that matches the language of your PDF. Mixed-language documents may need a different voice for some sections.
Know what happens in your browser
The selected PDF is parsed in the browser and is not sent to a PDF-processing upload endpoint by this page. The PDF libraries are loaded from public CDNs. Speech playback uses your browser or operating system voice engine; some voices may rely on network services, so check the privacy settings for your chosen voice.
Listen to study notes, books, reports, and other PDFs that contain selectable text.
Listen to selectable text in lecture notes, study guides, and course readings while following the highlighted sentence.
Use continuous reading to move through multi-page books, articles, and reports without selecting every sentence manually.
Listen to text-based reports and documents when you want an alternative to reading from the screen.
Choose a system voice that supports the language of your document. Voice and language choices vary by device.
Keep the active sentence visible while the browser reads it aloud. Keyboard users can also select a sentence to start reading.
Save the PDF’s extracted text as a plain TXT transcript or a Markdown document with page headings.
Encountering an unexpected hurdle with your document? Here are the most effective solutions and diagnostics.
Symptoms: A page is blank or says no selectable text was found
The PDF may be a scan made from page images. Run the file through an OCR PDF tool, download the searchable result, and upload it again.
Symptoms: The document cannot be opened for text extraction
Unlock the PDF with the correct password using a tool that you trust, then upload the unlocked copy. Do not upload confidential documents to services you do not trust.
Symptoms: The voice list is empty or speech does not start
Check that your browser supports the Web Speech API, your device has a speech voice installed, and the operating system volume is on. Refresh the page after installing new voices.
Symptoms: Columns, tables, or footnotes are read out of sequence
PDF text extraction follows the order encoded in the document and may not match its visual layout. Try a text-based PDF exported from the original source, or copy and correct the transcript before using it.
Symptoms: Playback pauses unexpectedly or a voice becomes unresponsive
Try pausing and playing again, choose another system voice, or refresh the page and re-upload the PDF. Browser speech engines can behave differently across devices.
Symptoms: Text extraction is slow or the browser runs low on memory
Try a smaller PDF, close unused tabs, or split the document into shorter sections. The tool currently accepts files up to 100 MB, but practical limits depend on your device.
Zero Data Scraping: The PDF is parsed in this browser tab. Speech playback uses your browser or operating system voice service, whose privacy behavior may vary.
Common questions regarding text-to-speech (TTS), narration accents, playback speed, and transcript export.
Upload a text-based PDF, wait for text extraction to finish, then press Play. The reader uses a voice available through your browser or device.
