Dropbox iOS Conversion of HEIC Photos to JPG on Portrait Mode Photos not Viewable on Sierra
I have my iPhone set to capture HEIC, and Dropbox client set to Save HEIC Photos As JPG. If you take a "Portrait Mode" photo on the iPhone in HEIC, and have Dropbox convert this to JPG, the JPG i...
In fact, there are many HEIC to JPG converter online and most of them are free. I also have the need to convert HEIC photos to JPG. But instead of the free tools, I selected Joyoshare HEIC Converter as it's lossless and supports many popular formats that others don't. It's easy to convert the HEIC photos to JPG or PNG or others with Joyoshare. Maybe you can have a test with its free version first.
You can change the format back to JPG but if you've already used the HEIC format, the only thing you can do is convert your images. There are few converters already and I found this Free HEIC Converter to JPG. This works perfectly as I was able to change the format of my images without losing the quality of my pics. It's free and does not require installing additional software as its an online tool.

Super User II
Super User IIAt one point there was an issue where app would change the extension to JPG but not actually convert the file (or did it convert the file but not change the extension, I don't remember). Either way, I thought that had been resolved. If you still have a JPG or HEIC image that was uploaded by Dropbox and you can't open it, try changing the file's extension just as a test.
So I have a file with a .jpg extension that cannot be opened Sierra but can on High Sierra.
Let's assume it is really a .heic file but has an incorrect .jpg extension.
Now I change it to .heic as you suggest.
What exactly would the next steps be? And how would those steps prove your theory?

There are no next steps. It was simply a suggestion for when you come across a JPG or HEIC file that wasn't recognized (by the file's extension) and couldn't be opened. Changing the extension may allow you to open the file because the extension would then match the file type and the operating system would then know how to handle the file.
Going back to look at it, the Dropbox iOS app was uploading HEIC files and renaming them to JPG, but not actually converting them. Changing the file's entension from JPG to HEIC allowed the file to be opened normally. No data was being lost. This issue was corrected.
On High Sierra, there was no problem opening the heic file, even with the .jpg extension. So changing the extension to .heic changed nothing (it still opened on High Sierra, and still could not be opened on Sierra).
But the real problem was that Dropbox was not converting heic files to jpg when the setting was on.
Now the problem has changed a little. Under most native setting conditions, Dropbox never converts the heic to jpg, so although it correctly keeps the .heic extension, the resulting file is not easily shareable.
I have since gone back to change the native phone settings to "most compatible (JPG/MP4)" until Dropbox can get it worked out. Also, it turns out that heic photos actually are of lower quality than jpg in many cases, and since I have 256GB, I'm not really concerned about space that much. The new video file would be important to me, however.
