Frequently Asked Questions
Will backing up my PDFs and images reduce their quality?
No, uploading PDF files and images to a cloud storage service like WPS Cloud, Google Drive, or iCloud retains their original resolution and quality. They are stored exactly as they are on your device.
How can I restore my backed-up PDF files to a new phone?
To restore your files, simply download the same cloud storage app (such as WPS Office) on your new device, log in with the same account credentials, and download the synced files directly to your new phone's local storage.
Can I back up my files using a physical cable instead of the cloud?
