How to Fix PDF Highlights Not Syncing from iPad Acrobat to Desktop
Question details
The user needs to resolve an issue where highlights added to a PDF on an iPad do not transfer to the desktop version of the application.

- Product
- Adobe Acrobat Reader
- Device & OS
- iPadOS and Desktop (Windows/Mac)
- Scenario
- Reviewing and annotating PDF documents across multiple devices using cloud synchronization.
- Observed behavior
- Highlights and annotations added to a PDF in the iPad app do not appear in the desktop comments tracker, forcing the user to manually add the annotations again.
Make sure both your iPad and desktop computer have an active, stable internet connection, as cloud synchronization cannot process offline changes.
Force Synchronization via Adobe Document Cloud
Trigger a manual sync by signing out, signing back in, and adding a new test annotation to push the updates to the cloud.
Often, the mobile app may lose its active connection token to the Document Cloud, preventing local highlights from being uploaded. A fresh login and a new document change will force the app to sync the latest version.
Open the Adobe Acrobat Reader app on your iPad, tap the profile icon in the top corner, sign out of your account, and then sign back in using the exact same credentials.
Navigate to the 'Files' tab, select 'Document Cloud', and open the specific PDF file you were working on.
Add a small, temporary highlight or text comment to the document. This action prompts the application to instantly push the latest changes to Adobe's servers.
Open Acrobat Reader on your desktop computer, ensure you are logged into the same Adobe account, open the file from the Document Cloud tab, and check the comments panel for your updates.

Update Acrobat Applications on Both Devices
Install the latest app updates to resolve known synchronization bugs between iPad and desktop platforms.
Sync PDF Highlights Seamlessly Across Devices with WPS Office
If you continue experiencing third-party sync issues, WPS Office provides a highly reliable, built-in cloud service. It ensures your PDF annotations, highlights, and edits are instantly updated and accessible across your iPad, Android device, and desktop computer.
- 1. Install WPS Office: Download and install WPS Office on both your iPad (via App Store) and your desktop computer.
- 2. Sign in to WPS Cloud: Open the application on both devices and log in using the same WPS account credentials.
- 3. Annotate on your iPad: Open your PDF file from the WPS Cloud folder on your iPad, use the highlight tool to mark important text, and close the file to auto-save.
- 4. Access on Desktop: Open WPS Office on your desktop and access the same file from your Cloud folder. All highlights will appear instantly.

Frequently Asked Questions
Why do my PDF comments disappear when moving the file from my iPad to my PC?
This usually happens if the PDF was saved locally in the 'On This Device' folder on your iPad rather than in a cloud service, or if the cloud sync was interrupted before completion. Always ensure the file is saved to the cloud before closing the app.
Do I need a premium subscription to sync highlights across devices?
No, basic viewing, highlighting, and syncing of annotations via Adobe Document Cloud or WPS Cloud is generally free, provided you are logged into the same account on both devices and have adequate cloud storage space.
How do I know if my PDF is actually saved in the cloud?
In your PDF reader application, check the file location listed under the document's properties or in the 'Files' tab. It should explicitly state the cloud service name (e.g., Document Cloud, WPS Cloud) rather than local device storage.
Can I use iCloud or Google Drive to sync PDF highlights instead of the app's native cloud?
Yes. If you open the PDF directly from a third-party cloud drive integration like iCloud or Google Drive on your iPad, highlights will save directly to that file. Ensure your desktop application opens the exact same file directly from that specific cloud folder.
