Solution 1Recommended

Update iPadOS and the OneNote App

Installing the latest software updates patches known rendering bugs that cause the application to freeze during PDF generation.

Software updates often contain fixes for background crashes and PDF rendering engine failures. Keeping both your operating system and the app updated is the primary defense against application freezes.

1
Check for iPadOS Updates

Open the 'Settings' app on your iPad, tap on 'General', and select 'Software Update'. If an update is available, tap 'Download and Install'.

2
Update Microsoft OneNote

Open the 'App Store', tap your profile picture in the top right corner, and scroll down to view pending updates. If OneNote is in the list, tap the 'Update' button next to it.

3
Restart the iPad

Press and hold the top power button and either volume button until the power-off slider appears. Drag the slider to turn off the device, then turn it back on and try sharing the PDF again.

Frequently Asked Questions

Why does OneNote get stuck on 'Preparing PDF' on my iPad?

This freezing issue is typically caused by a glitch in the app's internal PDF rendering engine, corrupted cache data, or an unstable internet connection interrupting the sync process before the file generation finishes.

Will offloading OneNote delete my un-synced notes?

No. Offloading removes only the application files while preserving your documents and local data. However, it is always highly recommended to ensure your notes are fully synced to OneDrive before modifying app installations to prevent accidental data loss.

Can I export OneNote pages as PDFs from a computer instead?

Yes. If the iPad application continues to fail, you can access your notebooks by logging into OneNote for Web via a browser, or by using the desktop versions (Windows or Mac) to successfully export and share your notes as PDF files.
