How to Fix PDF Read Out Loud Showing Blank Pages in Large Files
Question details
The user needs a bulk solution to fix the Read Out Loud feature, which incorrectly reports every page as blank in a large PDF document.

- Product
- PDF Reader
- Device & OS
- not provided
- Scenario
- Attempting to use the text-to-speech or Read Out Loud feature to listen to a 650-page PDF document.
- Observed behavior
- The screen reading tool announces each page as "blank" unless the reading order is manually changed page-by-page to Text or Paragraph.
Verify whether your PDF is a scanned image document or contains selectable text, as image-based PDFs cannot be read aloud without performing Optical Character Recognition (OCR) first.
Auto-Tag Document for Accessibility
Automatically adds accessibility tags to the entire PDF document to fix reading order issues in bulk without manually editing each page.
Read Out Loud heavily depends on a PDF's internal accessibility tags and logical reading order. When a document lacks these tags, the text-to-speech engine cannot find the text and assumes the page is blank.
Launch your advanced PDF editor, navigate to the Tools menu, and open the Accessibility or Action Wizard pane.
Select the "Autotag Document" option to scan the entire 650-page document and automatically generate structural tags for all pages simultaneously.
Save the document, close the accessibility tool, and re-launch the Read Out Loud feature to test the continuous reading flow.
Perform OCR on Scanned Documents
Converts scanned page images into readable, searchable text that text-to-speech tools can process.
Repair Document Structure via Accessibility Checker
Identifies and automatically repairs specific structural errors causing the PDF reader to misinterpret content.
Read Large PDFs Aloud Effortlessly with WPS Office
If you are struggling with complex accessibility tags or broken reading orders, WPS Office provides a streamlined PDF reader with an intelligent Text-to-Speech (TTS) engine and built-in OCR to effortlessly read large documents aloud without requiring manual tagging.
- 1. Open the Document: Launch WPS Office and open your large PDF document.
- 2. Run OCR if Necessary: If the document is a scanned image, use the "OCR" feature under the Tools tab to convert the entire document to readable text.
- 3. Activate Text-to-Speech: Navigate to the "Read" or "View" tab and click the "Read" button.
- 4. Adjust Settings: Use the reading toolbar to adjust the reading speed, select a comfortable voice, and let WPS Office read the document aloud.

Frequently Asked Questions
Why does my PDF reader say a page is blank when I can clearly see text?
This happens because the document lacks the hidden accessibility tags or reading order formatting required by screen readers. While visually present, the software's text-to-speech engine cannot logically detect the text blocks.
Do I have to manually fix the reading order for every single page in a large PDF?
Not necessarily. Advanced PDF editors offer bulk tools like "Autotag Document" which can generate text elements and reading structure across an entire document automatically.
Will converting the PDF to a Word document fix the Read Out Loud issue?
Yes, exporting the PDF to a Word document (.docx) often strips out complex PDF tag structures and allows native word processors to read the plain text aloud without encountering reading order errors.
