Forcing JPEG-only format on iPhone?

.mov is a video format, not a picture format, and has nothing to do with the HEIF/HEVC settings.

When you take a Live Photo, it’s actually a combination of a very short .mov video and a static picture.

I have an XR and have to take/send pics. in JPEG. I too have gone to settings>camera>and have selected most compatible as instructed for JPEG but pics. remain in JPG when I save. I can't send them where I need to in this format. Any thoughts. Thanks.

...selected most compatible as instructed for JPEG but pics. remain in JPG when I save.

There are actually no differences between the JPG and JPEG formats. The only difference is the number of characters used to represent them. You can manually change the extension from one to the other without affecting the actual file in any way.

To be even clearer, JPG and JPEG are EXACTLY the same thing. The actual standard is JPEG, but there was a time when Microsoft required all file types to be 3 characters or fewer, so just to accommodate older versions of Windows JPG was added as a synonym file type.

Thank you both for the helpful response. Have been told that they are both the same thing but I do get an error referring to the extension not being recognized. How do I change the extension as you mention Rysz?

Thanks.

You can change it in Finder. Drag out or export the pictures to the Desktop (or a folder on the desktop), then select a file and right-click on it to see the Get Info window. Finder can also be setup to show extensions, but that makes it rather messy for everything else. I’m sure there’s a script for changing the extensions on multiple files at once, but I don’t have it. I’m not aware of a method of doing this on the iPhone directly.

You may not have a choice here, but personally I would stay away from anything that doesn’t “know” these extensions stand for the same file format.

The third setting you listed is the one that turns HEIF/HEVC off in Camera app.

You're good to go!

I went into camera settings and changed the setting to "most compatible" but I'm still getting .mov pictures instead of .jpg. Why? What more must I do?
