Can OneDrive Upload iCloud Photos with Optimize iPhone Storage Enabled?
Question details
The user is trying to determine if the OneDrive iOS app can successfully upload full-resolution photos directly from iCloud when the iPhone is set to retain only optimized, low-resolution versions locally.

- Product
- OneDrive iOS App
- Device & OS
- iOS
- Scenario
- Backing up iPhone photos to Microsoft OneDrive while conserving local device storage using Apple's iCloud optimization.
- Observed behavior
- Microsoft documentation historically stated OneDrive cannot upload optimized photos, but the newer 'Upload From iCloud' option appears designed to request and back up the full-resolution photos, though explicit official confirmation is lacking.
Ensure your iPhone is connected to a stable Wi-Fi network and plugged into a power source, as downloading full-resolution photos from iCloud for backup can consume significant data and battery power.
Enable 'Upload From iCloud' in OneDrive Settings
Activate the dedicated iCloud upload feature in the OneDrive iOS app to request and back up full-resolution photos.
While OneDrive traditionally struggled with optimized iCloud photos, the newer 'Upload From iCloud' option is designed to request the full-resolution versions directly from Apple's servers before backing them up.
Since official documentation on this exact behavior is still sparse, the best approach is to enable the setting and verify the uploaded file sizes manually.
Launch the OneDrive app on your iPhone and tap your profile picture or the 'Me' icon at the top left corner, then select 'Settings'.
Navigate to the 'Camera Upload' menu to view your automatic photo backup preferences.
Find and toggle on the 'Upload From iCloud' option. Allow the app some time to process and request the files from Apple's servers.
Log into OneDrive on a computer, right-click one of the newly uploaded photos, and check its file properties to verify it is the full-resolution original and not a low-quality thumbnail.

Temporarily Disable 'Optimize iPhone Storage' to Force Download
If OneDrive fails to fetch full-resolution images, download them to your iPhone first by disabling the Apple storage optimization setting.
Manage Your Documents Effectively with WPS Office
While resolving your cloud storage and photo backup configurations on OneDrive, consider WPS Office for all your document management needs. It is a lightweight, free alternative to Microsoft Office that is fully compatible with your existing files and cloud drives.
- 1. Download WPS Office: Install WPS Office for free from the official website or your device's app store.
- 2. Connect Your Cloud: Open the app, go to the 'Open' or 'Cloud' tab, and select 'Add Cloud Storage'.
- 3. Link OneDrive: Choose OneDrive from the list, log in with your Microsoft account, and start editing your saved documents directly.

Frequently Asked Questions
Why does OneDrive say my photos are optimized for iCloud?
This message appears when your iPhone is configured to 'Optimize iPhone Storage'. To save space, iOS keeps low-resolution thumbnails on your local device while storing the high-resolution originals in iCloud. Historically, this prevented third-party apps like OneDrive from backing up the original quality files.
Can I back up iPhone photos to OneDrive in the background?
Yes, but Apple's iOS heavily restricts background app activity to save battery. To ensure continuous backup, enable 'Background App Refresh' for OneDrive in your iPhone settings, and occasionally open the OneDrive app so it can actively trigger the upload queue.
How do I check if my OneDrive backed-up photos are full resolution?
The easiest method is to log into your OneDrive account via a web browser on a computer. Select a recently backed-up photo, click the 'Info' icon to open the Details pane, and check the file size and pixel dimensions to see if they match a standard high-resolution image taken by your iPhone.
