Scenario

Observed behavior
OneDrive downloads the files in their original HEIC format and does not offer a built-in feature to automatically convert them to JPG or other formats during the transfer.

Solution 1Recommended

Download Locally and Use a Third-Party Converter

Because OneDrive cannot convert cloud files directly, you must download the HEIC files to your computer and use a dedicated conversion tool.

OneDrive is designed to preserve the exact file format that was uploaded from your iOS device. To change these HEIC files to a universally recognized format like JPG, the conversion must be done locally on your machine before you move the files to an external drive.

1
Download HEIC files from OneDrive

Open your web browser or the OneDrive desktop app, select the HEIC photos and videos you want to transfer, and click the 'Download' button to save them to your local hard drive.

2
Acquire a conversion tool

Download and install a trusted third-party HEIC to JPG image converter or video conversion software on your computer.

3
Convert the downloaded media

Launch the converter tool, import the HEIC files you just downloaded, choose 'JPG' (or another preferred format) as the output, and click 'Convert'.

4
Move to external drive

Plug your external drive into the computer, locate the newly converted files, and copy them directly onto the external drive.

Prevent Future HEIC Uploads: To stop your iPhone from taking HEIC photos entirely, go to Settings > Camera > Formats and select 'Most Compatible'. Future photos will be saved and uploaded as JPGs.

Frequently Asked Questions

Why does my iPhone upload photos to OneDrive in HEIC format?

Apple uses the High Efficiency Image Container (HEIC) format by default on newer iPhones. This format maintains high image quality while taking up significantly less storage space, and OneDrive uploads these original files to preserve their quality.

Can I convert HEIC to JPG directly inside the OneDrive app?

No, neither the OneDrive mobile app nor the web version offers a built-in feature to convert HEIC files to other formats. They function strictly as cloud storage and synchronization tools.

Does Windows natively support viewing HEIC files?

Windows 10 and Windows 11 can open HEIC files natively using the default Photos app, provided you have downloaded the free 'HEIF Image Extensions' from the Microsoft Store.

What is the best format to convert HEIC photos to for an external drive?

JPG (or JPEG) is universally recommended for external drives, as it is supported by almost every operating system, smart TV, digital photo frame, and media player currently available.
