“Microsoft Copilot” is versatile in its own right. The ability to perform a number of tasks faster and with enhanced precision makes the AI-powered assistant stand out. One of my favorite features of this AI assistant is its efficiency in summarizing, analyzing, and answering questions about PDF files, which makes it a noteworthy productivity tool.
While Copilot is adept at reading PDF files, there are times when it runs into unexpected issues. At times, the AI assistant refuses to read a PDF file; at other times, it tends to get stuck while loading. Worse, on some occasions, it throws an error message and fails to extract the document’s contents at all. This issue crops up whether you’re using Copilot on Windows, Microsoft Edge, Microsoft 365, or the web version.
How to Fix Copilot Unable to Read PDF File on Windows 11
So, what prevents Copilot from reading a PDF? Well, the problem occurs due to several factors such as –
- Unsupported PDF
- Outdated software
- Browser cache problems
- Permission restrictions
- Temporary service glitches
To troubleshoot the problem, we are going to address these very usual suspects.
1. Make Sure the PDF Isn’t Corrupted
Before going any further, ensure that the file itself is not damaged or incomplete. If the PDF was interrupted during download, improperly exported, or corrupted while being transferred, Copilot will fail to process its contents correctly. Hence, make sure to verify that the document opens normally before troubleshooting Copilot.
- To get going, open the PDF with the help of another PDF reader, such as Adobe Acrobat Reader or your web browser.
- Be sure to check whether every page loads correctly.
- Try scrolling through the entire document.
- If the PDF doesn’t open properly, I’d recommend you download it again from the original source.
- If you created the PDF yourself, do not forget to export or save it again before uploading it to Copilot.
2. Check Whether the PDF Contains Searchable Text
Be warned that not every PDF contains selectable text. Many documents are simply scanned images stored inside a PDF container. Since Copilot analyzes text instead of images, it may not be able to understand documents that haven’t been processed with Optical Character Recognition (OCR).
- Navigate to the PDF in question > try selecting a sentence with your mouse.
- If you cannot highlight any text, the document is likely image-based.
- Run the PDF through an OCR tool using Adobe Acrobat or another OCR application.
- Save the searchable version of the document.
- Upload the new PDF to Copilot again.
3. Update Microsoft Edge or Copilot
Older versions of Microsoft Edge or the Copilot application may contain bugs that interfere with PDF analysis. Microsoft regularly releases updates that improve compatibility, fix known issues, and enhance overall performance. That’s why installing the latest updates is always recommended.
- Open Microsoft Edge.
- Click the three-dot menu in the upper-right corner.
- Select Help and feedback > About Microsoft Edge.
- Allow Edge to automatically check for updates.
- Install any available updates.
- Restart the browser after the update finishes.
- Open Copilot and try reading the PDF again.
4. Clear Browser Cache and Cookies
Though the cached files and cookies play a pivotal role in delivering a fully personalized experience, you should make sure to clean them up from time to time to ensure they don’t become outdated or corrupted. Clearing the browser cache allows you to force Edge to download fresh website data, which often resolves unexpected loading issues.
- Head over to Microsoft Edge on your PC > press Ctrl + Shift + Delete > Cached images and files.
- Select Cookies and other site data if necessary > choose All time as the time range.
- Click Clear now > restart Edge > upload the PDF again.
5. Verify the PDF Size and File Permissions
Do you know that some Copilot services impose limits on PDF size or supported file types? So, be sure to take a close look at the PDF file size or the compatible file types.
That aside, if the PDF is password-protected, encrypted, or stored in a location without sufficient permissions, Copilot won’t be able to access its contents.
- Check the PDF’s file size.
- Remove password protection if applicable.
- Ensure you have permission to access the file.
- Save a local copy of the PDF on your computer.
- Rename the file using a simple name without special characters.
- Upload the local copy to Copilot.
6. Sign Out and Sign Back Into Your Microsoft Account
Keep in mind that the temporary authentication issues can prevent Copilot from accessing uploaded documents correctly. To ward off this issue, try refreshing your Microsoft account session, as it can resolve syncing problems and restore normal functionality.
- On your PC, launch Copilot or Microsoft Edge > click your profile icon.
- Select Sign out and close the browser completely.
- After that, restart your computer and launch Edge again.
- Sign back into your Microsoft account > Upload the PDF once more to figure out whether or not you have sorted out the issue.
7. Check Whether Microsoft Copilot Is Experiencing Service Issues
Just like any other service on the planet, Microsoft services also face temporary outages, maintenance periods, or server-side issues that affect PDF processing. Therefore, it would be apt to check the service status before spending more time troubleshooting locally.
- Launch a browser and head over to Microsoft’s official service status page.
- Check whether Copilot services are reporting any issues.
- Look for announcements regarding outages or maintenance.
- If an outage exists, wait until Microsoft resolves the issue.
- Retry opening your PDF after the service returns to normal.
Signing off…
There you go! I hope Copilot has begun to read PDFs with the needed proficiency on your Windows device. By removing the above-mentioned hurdles, you can get rid of this issue without breaking any sweat at all. If the problem still persists, do check the service status to ensure that a temporary outage is not spoiling your party.
