How do I delete duplicate photos in iCloud?

If you’re syncing your photos to iCloud, Gemini Photos makes it easier to clean up duplicates on there, too. But before you start cleaning up your pictures, you’ll want to verify you have iCloud Photos enabled:

  1. Open Settings on your iPhone.
  2. Tap [your name] > iCloud > Photos.
  3. Toggle iCloud Photos on (if it’s not already on).

If iCloud Photos isn’t already turned on, you’ll need to give your iPhone some time to download all your pictures before you open Gemini Photos and start getting rid of the duplicates and clutter.

Can Apple Photos detect duplicates?

At this point in time, Apple Photos doesn’t provide an easy way to view or sort through duplicates. Unless you scroll through each picture and remove them individually, there’s no easy or quick way to clean up duplicates using the native app.

Why you have duplicate iPhone photos

Stumbling across duplicate pictures on your iPhone can be frustrating, but not knowing how they got there — or what you can do to stop getting duplicates — can be just as annoying. Here are a couple of common causes for duplicate images.

Reason 1. iCloud sync

In theory, iCloud should recognize when your iPhone is trying to upload a duplicate picture. But, from time to time, they still sneak in. 

How to prevent duplicate photos: Upload from one source

While it might be tempting to manually sync your iPhone photos to your computer via the USB, don’t do this if you have iCloud Photos turned on. This is especially true if you have iCloud Photos turned on, on both your iPhone and computer. It’s best to just let one device upload photos iCloud and all your other devices download from iCloud.

Reason 2. Multiple cloud services

If you’re using multiple cloud services, such as iCloud and Google Photos, duplicates become more likely. Because your iPhone is uploading pictures to two different locations, it will occasionally see the photo as two different images because they’re being synced from different places. 

How to prevent duplicate photos: Use one cloud service on your phone

The best way to prevent duplicates due to multiple cloud services is to use only one automatic service on your iPhone. If you want to use another cloud service as a backup, it’s best to either do it manually or only have your computer signed in to the two services.

Reason 3. The HDR setting is turned on

HDR is a camera effect for your photos. It stands for High Dynamic Range, which, in simplest terms, means that when you take a picture, the camera is taking multiple images and combining them into one photo. This gives your picture a sharper, higher contrast. 

In iPhone 8 and older, HDR is a feature you can switch on and off. When it's on, it creates an HDR photo, while also saving the original photo. This means you’re saving two similar-looking versions of the same picture. And while they’re not exact duplicates, you probably don’t want to keep the original and the HDR photo.

How to prevent duplicate photos: Turn off Auto HDR

Fortunately, you can turn off Automatic HDR, allowing you to choose when you want to use HDR so you don’t end up with multiple similar-looking pictures:

  1. Open the Settings app.
  2. Tap Camera.
  3. Toggle off Auto HDR.
  4. Open the Camera app.
  5. Tap HDR to turn it on or off.

Another option you have is to turn off the setting to Keep Normal Photo altogether. That way, once you take an HDR picture, it only keeps a single copy.

  1. Open Settings.
  2. Tap Camera.
  3. Toggle Keep Normal Photo off.

Reason 4. Photo editing

If you use a third-party app like VSCO to edit your photos, you’re likely to end up with duplicates. After you’ve finished editing the pictures, you typically need to save them to your Camera Roll again to share them with friends or on social media, which can create multiple versions of the same photo.

Like with HDR photos, pictures edited with a third-party app are saved back to your Camera Roll, creating a similar picture. So while it’s not an exact duplicate, it’s still a similar image taking up twice the storage space.

How to prevent duplicate photos: Edit in the Photos app

While the Photos app may not have the breadth of editing capabilities, it is still a powerful tool. And when you edit in the Photos app, it saves over the original by default to avoid the creation of duplicates.

  1. Open the Photos app.
  2. Select the picture you want to edit.
  3. Tap Edit in the top-right corner.
  4. Make your adjustment and then tap Done.

The nice thing about Photos is you can always revert the image back to what you started with, so don’t be afraid to play around and experiment with various edits on your pictures.

Using the iPhone camera to take pictures is fun and has never been easier. But dealing with duplicate photos can be a headache. Hopefully, this article has helped you figure out quicker ways to clean them up, so you can get back to enjoying all of the memories you’ve captured on your iPhone.
