Find and Delete Photos Duplicate HEIC on Mac

Why Mac Photos Duplicates HEIC Files?

High Sierra 10.13 and later versions are compatible with HEIC format, helping you compress image size and save much space on Mac. But it's prone to duplicate HEIC and JPEG files if you transfer HEIC from iPhone to Mac using two mixed methods.

For the first time, you transfer HEIC photos via My Photo Stream. They will be converted to JPEG format automatically, as My Photo Stream doesn't support HEIC.

The second time, you import HEIC files to Mac by connecting the device to USB or through iCloud shot Library. The images will remain in HEIC format. If some photos are transferred again accidentally, they won't be overwritten, because they are two different formats- HEIC and JPEG.

How to Avoid Apple Photos HEIC Duplicates on Mac?

  • Set the iPhone to only take pictures as JPEG. (Not a good way. For photos of the same quality, the HEIC size is half that of JPEG.)
  • Disable My Photo Stream and merely transfer HEIC photos from iPhone to Mac via iCloud Photo Library or USB
  • On your iPhone, go to "Settings" > "Photos" > "Transfer to Mac or PC" > choose "Keep Originals". (When you import HEIC files to Mac by USB, they might be changed to JPEG or H.264 formats sometimes.)

How to Manually Remove Photos Duplicate HEIC on Mac

  • Step 1. Launch the Photos app on your Mac.
  • Step 2. Head over to “File” at the top of the screen > select “New Smart Album”.
  • Step 3. From the pop-up menu, set the condition to "Filename includes .heic".
  • Step 4. Select all photos to duplicate HEICs in the smart album and delete them with the key combination Ctrl + Delete or Backspace.

Bear in mind that the manual method can only filter out pictures in the same format. But we mentioned above that HEIC photos are mainly duplicated with JPEG on Mac. So we'd better use a HEIC duplicate finder software to find similar images, rather than being limited to the identical format.
