HEIC offers better compression than JPG. HEIC photos use less storage space without losing the visual quality. That’s why iOS 11 and macOS 10.13 introduced support for the HEIC format in 2017. However, the HEIC and JPG duplicates issue has been around since then.

It is an issue where people end up having both a JPG version and a HEIC version of their photos after they import photos from iPhone to Mac.

This article mainly shows you how to easily find and mass delete the existing HEIC JPG duplicates on Mac. It also talks about how to avoid duplicates in future imports. In addition, it talks about how to delete HEIC files duplicates on Windows PC and iPhone.

1. Launch the Photos app on your Mac.

2. Head over to File at the top of the screen and select New Smart Album.

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 pictures by format. There is no guarantee that it will work correctly. HEIC photos are mainly duplicated with JPEG on Mac. So we’d better use HEIC duplicate finder software, rather than being limited to the identical format.


Why does Mac Photos duplicate HEIC files?

iOS 11 and later support shooting in HEIF (with the extension .heic) and JPEG (with the extension .jpg). HEIC is used by default. macOS High Sierra and later also support HEIC to help compress image size and save space. However, it’s prone to duplicate HEIC and JPG files if you transfer HEIC from iPhone to Mac using two mixed methods.

For the first time, you sync HEIC photos via My Photo Stream. They will be converted to JPG 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 Photos. This way, the images will remain in HEIC format. The already existing photos will be imported again because they are considered new photos due to being in different formats: HEIC and JPG.


How to avoid Apple Photos HEIC duplicates on Mac

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