How to Save PDF Highlights and Notes to Cloud on Amazon Fire Tablet
Question details
The user is unable to save PDF annotations, such as highlights and notes, to the cloud when using a PDF reader on an Amazon Fire tablet.

- Product
- PDF Reader
- Device & OS
- Amazon Fire OS
- Scenario
- Adding highlights and notes to a PDF document and attempting to sync those changes to a cloud storage service.
- Observed behavior
- Highlights and notes disappear when the PDF is reopened, and cloud-saving options appear disabled or unavailable.
Verify that your Amazon Fire tablet is connected to a stable internet network and that you are actively logged into your cloud storage account within the PDF application.
Verify Cloud Account Login and Network Settings
Ensuring you are properly authenticated and connected to a reliable network resolves most synchronization failures.
Cloud synchronization requires an active session with your document cloud provider. If your login token expires or the network connection drops while saving, the app may fail to upload your highlights and notes, causing them to disappear when reopening.
Open your PDF reader app, navigate to the Profile or Settings menu, and verify that you are signed into your cloud account. If signed out, log back in.
If you are on a Wi-Fi network, try disconnecting and reconnecting, or temporarily switch to mobile data (if available on your device) to rule out network restrictions.
Tap the cloud or sync icon usually located at the top menu bar of the PDF reader to manually push pending changes to the cloud server.

Check PDF File Permissions and Location
Determine if the issue is specific to a single PDF document or its storage location.

- 2. Annotate the Document: Navigate to the 'Annotate' tab at the top menu to access highlighting, underlining, and note-taking tools.

Frequently Asked Questions
Why do my PDF highlights disappear when I reopen the file?
This typically occurs if the file was closed before the application could finish syncing the changes to the cloud, or if the document is saved as read-only. Always wait for the sync completion indicator before exiting.
How do I fix the 'Save to Document Cloud' option being disabled?
The option may be grayed out if you are not signed into your cloud account, lack an internet connection, or if the PDF has security restrictions preventing modifications. Verify your login status and network connection first.
Can I edit and save a read-only PDF?
You cannot save modifications directly to a read-only or securely locked PDF. You must use the 'Save As' feature to create a new, editable local or cloud copy before applying your highlights.
Does WPS Office support saving PDF edits to cloud services?
Yes, WPS Office seamlessly integrates with WPS Cloud, Google Drive, and Dropbox, allowing you to edit PDFs and automatically sync your highlights and notes across devices.
