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.
Can I adjust the reading speed?
Yes, from 0.75× up to 2×. Changes take effect immediately, even mid-sentence, so you can slow down for a dense passage and speed back up without restarting.
Can I start from a specific page?
Yes. Click any page in the text panel and reading begins there rather than from the start, which is the fastest way to pick up where you left off in a long document.
How large a PDF can it handle?
Files up to around 100 MB work. Extraction happens on your own device, so a very large document may take a few seconds to process depending on your hardware.
Does it work on a phone or tablet?
Yes. The layout is responsive and speech synthesis is supported on modern mobile browsers, though the available voices are whatever your device provides.
