How to Fix Low-Quality PDF Images Inserted into OneNote
Question details
Users experience blurry or unreadable text when inserting a PDF document into OneNote, making it difficult to read or annotate the file.

- Product
- Microsoft OneNote
- Device & OS
- Android
- Scenario
- Inserting a PDF file into a OneNote notebook to read or annotate on a mobile device.
- Observed behavior
- The text in the PDF appears blurry and low-quality compared to viewing it in a standard PDF reader like Adobe Reader.
Ensure you have the original PDF file saved locally on your Android device and check that your OneNote application is updated to the latest version.
Insert the PDF as a File Printout
Using the printout feature often yields a much better resolution than inserting standard image captures of the PDF pages.
OneNote treats standard image inserts differently than printouts. A printout extracts the pages directly from the source file, which typically maintains better fidelity and text readability.
Launch the OneNote app on your Android device and navigate to the page where you want to add the document.
Tap anywhere on the page to bring up the text cursor and reveal the toolbar above your keyboard.
Tap the paperclip (Attachment) icon on the toolbar and browse your device for the target PDF.
When prompted, select 'Insert as Printout' instead of attaching it as a file. Wait for OneNote to process and display the pages.

Verify Rendering in OneNote for the Web
Check if the resolution issue is isolated to the mobile app's rendering engine by viewing the notebook in a web browser.
Read and Annotate PDFs Clearly with WPS Office
If OneNote continues to compress your documents and cause blurriness, consider using WPS Office. It includes a powerful, built-in PDF reader that maintains crisp, vector-quality text while allowing you to annotate, highlight, and manage your documents for free.
- 1. Download and install: Get WPS Office from the Google Play Store or official website and launch the application.
- 2. Open your PDF: Tap 'Open' on the home screen and select your PDF file from your device storage to view it in full native resolution.
- 3. Annotate directly: Use the 'Tools' menu to access the 'Annotation' tab, where you can highlight text, draw, and add notes without losing quality.

Frequently Asked Questions
Why does my PDF look blurry in OneNote but clear in Adobe Reader?
OneNote often renders PDFs as static images or printouts and may compress them to optimize cloud syncing and save storage space. Dedicated PDF software like Adobe Reader renders vector text dynamically, maintaining sharpness at any zoom level.
How can I prevent OneNote from compressing my inserted files?
While the Android app has limited configuration options, you can open OneNote on your desktop PC, navigate to File > Options > Advanced, and check 'Disable image compression' or adjust the default printout resolution to maintain higher quality for future inserts.
Can I convert the PDF to editable text in OneNote to fix the blurriness?
Yes, if you insert the PDF as a printout, you can right-click the image (on the desktop version) and select 'Copy Text from Picture' to paste it as editable text. This feature relies on OCR and may not be fully available directly within the Android app.
