Why OneDrive Changes iPhone Photo File Names During Upload
Question details
Users need to know why their iPhone photos are automatically renamed when uploaded to OneDrive and how to prevent or address it.

- Product
- OneDrive for iOS
- Device & OS
- iOS
- Scenario
- Backing up iPhone photos to cloud storage using the Camera Upload feature in the OneDrive app.
- Observed behavior
- Original iPhone photo names, such as IMG_3950.jpg, are automatically changed to date-and-time-based names ending with _iOS.jpg based on server time.
Verify your current OneDrive app version and gather a few specific examples of the original photo names and their newly renamed versions on your iPhone.
Report the Renaming Issue to OneDrive Support
Since there is no built-in app setting to prevent this automatic file renaming, contacting support is the recommended way to request assistance and log the issue.
During the camera-roll backup process on iOS, OneDrive automatically renames image files to a timestamp format ending in _iOS.jpg. Because Microsoft does not currently provide an option to toggle this off within the mobile app, escalating your feedback to the development team via official support is the most effective approach.
Navigate to OneDrive.com in your web browser and sign in to your Microsoft account. Click on the Help (?) icon located at the top of the page.
From the help menu panel, select the option labeled 'Email OneDrive support' to open a new support ticket.
In your message, clearly include concrete examples of the original iPhone file names (e.g., IMG_3950.jpg) alongside their newly renamed versions.
Specify your iPhone model, current iOS version, the OneDrive app version you are using, and the exact dates the uploads occurred.

Frequently Asked Questions
Can I turn off the automatic renaming of photos in OneDrive for iOS?
Currently, OneDrive for iOS does not offer an internal app option or setting to prevent the app from automatically renaming photos during the camera-roll backup process.
Why does the timestamp on my renamed OneDrive photo differ from when the picture was taken?
The generated timestamp in the new filename is typically based on the Microsoft server's date and time when the file is processed for upload, rather than the local time the photo was captured on your iPhone.
What information should I include when emailing OneDrive support about this renaming behavior?
You should include exact examples of the original filename (e.g., IMG_3950.jpg) and the renamed file, your specific iPhone device model, iOS version, the OneDrive app version, and the dates of the uploads.
