Question details

Users are unable to upload scanned PDFs to OneDrive using the Office Lens app, despite photo uploads working perfectly.

Product: Office Lens and OneDrive
Device & OS: iOS and Android
Scenario: Attempting to scan a document and export it directly as a PDF to OneDrive from the Office Lens mobile application.
Observed behavior: The application successfully uploads standard photos but throws an upload error when trying to save scans as PDFs. Standard troubleshooting steps such as clearing app data, reinstalling the app, or signing in again do not resolve the problem.

Before you start

Verify that your OneDrive account has sufficient available storage space and that you are connected to a stable Wi-Fi network before attempting to re-upload your files.

Solution 1Recommended

Use the Built-in OneDrive Document Scanner

Since the issue is a known limitation within the Office Lens app, using the native scanning feature inside the OneDrive app is the most reliable workaround to save PDFs directly to your cloud.

Microsoft integrates its scanning technology directly into the OneDrive mobile app. Bypassing the standalone Office Lens app often avoids the PDF processing and sync errors entirely.

Open OneDrive

Launch the Microsoft OneDrive app on your Android or iOS device.

Launch the Scanner

Tap the Camera icon located at the bottom of the OneDrive home screen.

Capture the Document

Swipe to select the 'Document' mode, align your physical document within the frame, and tap the capture button.

Save as PDF

Adjust the borders if necessary, tap 'Done', choose your desired OneDrive folder, and save the file directly as a PDF.

Seamless Sync: Scanning directly from the OneDrive app ensures the file is immediately synced to your cloud storage without needing third-party application handoffs.

Solution 2

Report the Bug to Microsoft Support

Because the issue persists across different operating systems and application versions, reporting the bug helps Microsoft developers identify and patch the backend limitation.

Frequently Asked Questions

Why does Office Lens upload photos but fail on PDFs?

PDFs require additional processing, formatting, and file conversion within the app before uploading. A bug or service limitation in certain versions of Office Lens disrupts this specific conversion and synchronization process with OneDrive servers.

Will clearing my Office Lens app data fix the PDF upload error?

In most cases involving this specific issue, clearing the app data, restarting your device, or reinstalling the app does not resolve the problem, as it is typically a server-side or cross-platform application bug rather than a local cache issue.

Is there a way to recover the scanned PDFs that failed to upload in Office Lens?

If your PDFs are stuck in the Office Lens 'My Files' gallery or upload queue, you can try tapping the share or export icon next to the file to send it directly to another app, such as your email or a local file manager, bypassing the broken OneDrive upload mechanism.
