How to Fix Low-Resolution Images and PDFs in OneNote Android
Question details
Users need a way to resolve blurry, low-resolution rendering of images and PDF files in the OneNote Android app to make documents readable for studying.
- Product
- OneNote
- Device & OS
- Android
- Scenario
- Reading, studying, and reviewing PDF documents or image files imported into mobile notebooks.
- Observed behavior
- Images and PDF files appear blurry and render at a very low resolution, making text illegible, and the issue persists even after reinstalling the application.
Ensure your device is connected to a stable Wi-Fi network and manually synchronize all your existing OneNote notebooks to OneDrive to prevent any accidental data loss before clearing app data.
Update the App and Clear Cache and Data
Updating OneNote to the latest version and clearing corrupt local data can force the app to redownload high-resolution assets from the cloud.
Rendering issues on Android often stem from a corrupted local app cache or an outdated app version struggling to load large PDF printouts properly. Forcing a refresh by clearing the data will prompt OneNote to sync fresh, clear copies of your files.
Open the OneNote app, tap your profile picture or the three-dot menu, select 'Settings', and choose 'Sync All' to back up your current notes to the cloud.
Open the Google Play Store, search for 'Microsoft OneNote', and tap the 'Update' button if a new version is available.
Navigate to your Android device 'Settings', tap on 'Apps' or 'App Management', find 'OneNote', select 'Storage & cache', and tap 'Clear Cache' followed by 'Clear Data'.
Relaunch the OneNote app, sign in with your Microsoft credentials, and allow the app enough time to fully synchronize and download your notebooks.
Contact Microsoft 365 Support
If standard troubleshooting fails, the problem may be a known server-side compression issue requiring official Microsoft support.

If OneNote continues to compress and blur your study materials, consider switching to WPS Office.

- 2. Open Your Document: Launch WPS Office, tap on the 'PDF' tab or 'Files' section, and select your document.
- 3. Read and Annotate: Enjoy full-resolution reading and use the built-in highlight and pen tools to annotate your study materials clearly.
Frequently Asked Questions
Why do PDF printouts look blurry in OneNote for Android?
To save bandwidth and storage space on mobile devices, OneNote sometimes heavily compresses large PDF printouts and images during synchronization, which causes them to appear blurry on Android screens.
Will clearing data in the OneNote app delete my study notes?
Clearing app data will remove locally stored notebooks from your device. However, as long as you have completely synced your notebooks to OneDrive beforehand, your notes are safely backed up in the cloud and will be restored when you sign back in.
Can I disable image compression in the OneNote Android app?
Currently, the OneNote mobile app does not offer a native setting to disable image or PDF compression. This feature is primarily manageable only within the desktop versions of OneNote through advanced settings.
What is the best workaround if OneNote continues to render blurry PDFs?
If OneNote cannot resolve the quality issue, using a dedicated PDF reader or an all-in-one suite like WPS Office is highly recommended. These apps handle PDF rendering natively without relying on heavy cloud compression.
