Why Did My iPhone Photos Turn Into JPEG on My PC? Keep Originals Explained

When you import HEIF photos from an iPhone over USB into Photos, Image Capture or a PC, Apple says the media might be converted to JPEG. If you do not want that, go to Settings, tap Apps, tap Photos, scroll down and tap Keep Originals. Only the USB route has that switch: iCloud Photos and OneDrive for iOS keep the original format, and AirDrop, Messages and email convert only when the receiving device cannot read the new format.

The guide on HEIC vs JPEG and why a photo will not open covers what the format is and how to switch the camera back to JPEG. This one is about what happens to the file once it leaves the phone. It is based on Apple's page on HEIF and HEVC media (published December 5, 2025, checked October 2026) and Microsoft's OneDrive support page.

1. Four routes, four outcomes

Apple's page describes what happens on each path. Putting them side by side is the quickest way to see why the same photo can end up as a HEIC on one computer and a JPEG on another.

That is four routes with three different behaviors, and only one of them, the USB import, is controlled by a setting on the phone.

2. What "might be converted" means

Apple's wording is deliberately cautious: the media "might be converted." The page does not publish a rule for exactly when conversion happens on a USB import, so it is not safe to assume either result. The only way to be certain which file you will get is to set the option yourself. If you need the original HEIC every time, turn Keep Originals on. If you need a JPEG every time, the reliable fix is to change what the camera saves in the first place.

3. How to turn on Keep Originals

Apple gives the path in four taps on a current iPhone:

1. Open Settings.
2. Tap Apps.
3. Tap Photos.
4. Scroll to the bottom and tap Keep Originals.

That is the path on Apple's page as of October 2026; menu names can differ on other iOS versions.

4. How to get JPEG every time

Keep Originals does the opposite of what most people with this problem want. If your goal is a JPEG on the computer, Apple's page gives the camera-level fix: open Settings, tap Camera, tap Formats, then tap Most Compatible. Apple says all new photos and videos will then use JPEG or H.264. Two limits apply. The option is available only on iPhones and iPads that can capture HEIF or HEVC in the first place, and it does not change photos you have already taken.

For photos already on the phone, Apple describes converting by exporting. On a Mac, open the HEIF image in Photos or Preview, choose File > Export, then pick a format such as JPEG or PNG before saving.

5. Which iPhones are affected

Apple's list of devices that can capture HEIF or HEVC begins with the iPhone 7 or iPhone 7 Plus and later, along with the iPad (6th generation) or later, among other models. If you have one of those, new photos are HEIC unless you have switched to Most Compatible. Apple's list does not include earlier models.

6. Why OneDrive users still see HEIC

Microsoft's page says OneDrive for iOS uploads HEIF photos in their original format, instead of converting to JPG, to preserve the image quality and save storage space. It also notes that some iOS devices no longer have the option to save images as JPG. If you use a non-Apple device such as an Android phone or a Windows PC, you can preview HEIF and HEVC files in OneDrive and store them on your device, but you may not be able to open them without additional apps.

Microsoft gives two practical answers. You can view the files in the OneDrive website in any browser. To open downloaded HEIF or HEVC files on a Windows computer, you may need to install a codec, and Microsoft says codecs are available from Microsoft and from other third-party app developers. Microsoft's page also repeats the camera-side fix: on an iOS device, open Settings, tap Camera, then Format, and under Camera Capture tap Most Compatible, though some devices no longer offer that option.

7. A quick way to choose

• You want the highest quality and use Apple software or iCloud Photos: leave the camera on High Efficiency and turn on Keep Originals for USB imports.
• You send photos to a Windows PC or other apps that struggle with HEIC: set the camera to Most Compatible, so there is nothing to convert later.
• You have a handful of old HEIC files: export them to JPEG on a Mac, or open them from the OneDrive website.

8. Key takeaways

• Over USB, Apple says HEIF photos might be converted to JPEG; Keep Originals (Settings, Apps, Photos) stops that.
• iCloud Photos keeps the original format, resolution and frame rate.
• AirDrop, Messages and email convert only if the receiving device does not support the newer formats.
• OneDrive for iOS uploads HEIF in its original format, and Windows may need a codec to open the download.
• For JPEG every time, use Settings, Camera, Formats, Most Compatible on devices that offer it.
