Switch to Dedicated Copilot View for Accurate Scanned PDF Analysis
Use the full Copilot view to avoid low-resolution OCR errors on scans.
If Copilot fails to summarize a scanned PDF in OneDrive or Teams, open the file in the standalone Copilot interface to ensure it analyzes the full document instead of a low-quality preview image.
The Scenario
You have a scanned PDF document in OneDrive that you need to summarize, but the 'Summarize' button in the file preview is giving you errors about low resolution.
Before & after
Users often click the 'Summarize' button directly in OneDrive or SharePoint previews, which often fails on scanned PDFs and takes 5–10 minutes of troubleshooting.
By opening the file in the full Copilot web or app view, the AI processes the high-resolution source document, enabling accurate OCR and full-document extraction in 1–2 minutes.
The Prompt
Summarize the attached scanned PDF and extract the key data points, ensuring you use OCR to read all text accurately: [UPLOAD_FILE]
The integrated Copilot buttons in OneDrive and SharePoint often rely on low-resolution preview images rather than the full file metadata. For scanned PDFs or complex images, switching to the dedicated Copilot chat interface ensures the engine performs a deep scan of the actual file.
