How to Synchronize PDF Highlights with Adobe Document Cloud
Question details
The user wants to know if highlights, comments, and markups added to a PDF will automatically synchronize across different devices.

- Product
- Adobe Document Cloud
- Device & OS
- not provided
- Scenario
- Adding highlights and markups to a PDF document and expecting those changes to appear on other devices like mobile tablets or web browsers.
- Observed behavior
- Changes made to a locally saved PDF do not synchronize across devices, requiring the document to be properly hosted and accessed via cloud storage.
Ensure you are signed in to your Adobe account on all devices and have a stable internet connection to allow real-time synchronization.
Upload and Edit via Adobe Document Cloud
To enable cross-device synchronization, you must upload the local PDF to the cloud and edit that specific cloud-stored copy.
PDF files saved locally on your device will not synchronize changes automatically. To share highlights and comments across devices, the active file must reside in Adobe Document Cloud.
Open the Adobe Acrobat Reader app and upload your local PDF document directly to Document Cloud.
Navigate to the Document Cloud section within the app and open the newly uploaded file. Do not open the old local version.
Use the highlighting and markup tools to annotate the document. Because the file is opened from the cloud, changes will register to your account.
Log in to the same Adobe account on a different device or through the web browser to view the synchronized highlights.

Frequently Asked Questions
Why aren't my PDF highlights syncing across my devices?
If you are opening a PDF file from your device's local storage, changes will not sync. You must open the file directly from Document Cloud or your cloud storage provider for edits to synchronize.
Do I have to re-upload the file every time I highlight something new?
No. Once the file is uploaded to Document Cloud, you only need to ensure you are opening the cloud version. Any subsequent highlights or comments will sync automatically as long as you are connected to the internet.
If my local PDF already has highlights, will they disappear when I upload it to the cloud?
No, if you upload a local PDF file that already contains highlights, Document Cloud will preserve and display those highlighted sections perfectly.
