Scenario
Highlighting text in a PDF document and subsequently closing and reopening the file.
Observed behavior
The highlighted annotations are not saved or synchronized, resulting in their disappearance when the file is opened again.
Before you start

Ensure you have a stable internet connection if you are editing files directly from a cloud storage service, and verify that you are logged into the correct user account on your PDF software.

Solution 1Recommended

Ensure Proper Saving and Cloud Synchronization

Manually save your document and wait for cloud synchronization to complete before exiting the application.

Often, PDF highlights disappear because the application is closed before the changes can be written to the local disk or synced to the cloud.

1
Manually save the file

Click the Save icon in your PDF editor or press Ctrl+S (Windows) / Cmd+S (Mac) immediately after applying your highlights.

2
Check sync status

If you are editing a cloud document, look for the synchronization icon or status bar in the software to confirm the upload has reached 100%.

3
Verify your account

Navigate to the account settings within your PDF application to ensure you are signed into the correct account where the cloud file is hosted.

Synchronization Complete: Waiting for the sync icon to display a checkmark guarantees your annotations are securely backed up.

Frequently Asked Questions

Why do my PDF highlights show up on my PC but not on my mobile device?

This usually happens due to incomplete cloud synchronization. Ensure the file has fully uploaded and synced from your PC before opening it on your mobile device.

Can the document's security settings prevent highlights from saving?

Yes. If the PDF is restricted by the author or marked as 'Read-Only' in your system, you might be able to add highlights temporarily in the viewer, but they will not be saved to the file when you close it.

How can I permanently flatten highlights so they cannot be removed?

You can preserve annotations permanently by printing the document to a new PDF. Go to 'Print', choose 'Microsoft Print to PDF' or 'WPS PDF' as your printer, and save the output to 'flatten' the highlights into the core document.

Do highlights disappear if I use a different PDF viewer to open the file?

Sometimes different PDF software renders annotations differently. However, standard PDF highlights saved correctly should appear across all major PDF readers, including WPS Office, Adobe Acrobat, and modern web browsers.
