How to find and delete duplicate photos on iPhone
Duplicate photos are the most harmless clutter on a phone. Nothing is lost when you keep one copy and remove the others. The tricky part is finding them, and deciding which version deserves to stay. This guide covers the tools that already exist on your iPhone, what they miss, and how Poofora handles the rest.
Why duplicates appear
Most duplicates are not mistakes you made on purpose. They come from everyday habits:
- A photo saved from a chat twice, or saved once from each of two chats.
- A photo you edited, when the original remains next to the edited version.
- Burst shots, where the camera takes many frames in a second.
- Several attempts at the same group photo or the same sunset.
- Imports from another device, an old backup or a shared album.
There are two kinds worth separating. Exact duplicates are the same file twice. Similar photos are different files of nearly the same moment, such as five frames of a child blowing out candles. Both take space, but they need different decisions.
The built-in way: the Duplicates album
On iOS 16 and later, Photos has a Duplicates album. Open Photos, tap Albums, scroll to Utilities and tap Duplicates. Each pair or set is shown together, with a Merge button.
Merge keeps the best quality version and combines the relevant information, such as favorites and captions. The extra copies go to Recently Deleted, so you can still recover them for a limited time.
This works well for exact copies, and it is a good first pass because it is free and already installed. It has limits:
- It is built to find the same photo, not shots taken a moment apart.
- It does not tell you which of five similar frames has the best smile.
- You merge one set at a time unless you select several.
If you are on an older version of iOS, the Duplicates album is not there, and you will need to compare by eye or use an app.
The manual way
If you want to go through the library yourself, sort out the most likely places. Open Recents and look for photos that appear twice in a row. Check the Bursts album, where each burst can be several photos. Look at Media Types and Live Photos for items that are also saved as stills. In each case, you open the candidates side by side, pick one, and delete the others.
This is accurate, but it is slow when the library has thousands of photos. For a phone with ten years of pictures, it can take a very long time.
How Poofora finds duplicates and similar photos
Poofora scans your library on the iPhone using Apple’s built-in frameworks. It groups photos that look the same or nearly the same, and it shows each group on one screen.
For every group it suggests a Best photo to keep. That suggestion takes sharpness into account, and for photos with people it looks at faces and eyes only to judge whether the shot is sharp or someone blinked. It does not identify anyone. The suggestion is only a suggestion: you can choose another photo to keep, and you can look at any photo more closely before you decide.
Here is what happens next:
- You mark the photos you want gone. Nothing is deleted at this point.
- The marked photos wait on the Review screen, where you can return any of them to the library.
- You tap Delete and confirm. iOS then asks you to confirm again.
Photos that you have marked as favorites, photos that sit in albums, and photos you chose to keep are protected, and Poofora does not mark them for you. If you want to remove one of those, you can still do it yourself.
Poofora also looks for similar videos, and it handles bursts, so the same logic applies to the shots that Photos leaves alone.
How to choose which photo to keep
Whether you use Poofora or go through by hand, a few quick questions decide most groups:
- Is anyone blinking, or mid-sentence with an odd expression?
- Is the subject sharp, or did the camera focus on the background?
- Is the framing better in one of them?
- Is one of them edited, and do you prefer the edit?
When two photos are equal, keep the earlier or the original. If you are not sure about a group, leave it. You can come back to it, and keeping a few extra photos costs very little.
What happens after you delete
Deleted photos move to Recently Deleted in Photos, where iOS keeps them for a limited time. That is your safety net. If you realize you deleted the wrong one, open Photos, Albums, Recently Deleted, select it and tap Recover. Poofora cannot restore photos for you, since the recovery is done by iOS in Photos.
Storage does not come back immediately. The space is freed when the photos leave Recently Deleted. Any size figure you see in Poofora is an estimate. The guide to deleted photos and iCloud explains why this matters, especially if you use iCloud Photos.
If you use iCloud Photos
With iCloud Photos on, your library is shared across your Apple devices. When you delete a duplicate on one device, it is removed everywhere. That is usually what you want for a duplicate, but be sure you are looking at the right one first.
Photos that exist only in iCloud may need an internet connection to preview in Poofora. For photos stored on your iPhone, Poofora works without internet.
A short plan
- Run the Duplicates album and merge exact copies.
- Go through Bursts and keep one or two per burst.
- Use Poofora to review the groups of similar photos.
- Check the Review list once more before you tap Delete.
- Look at Recently Deleted after a few days, then empty it when you are sure.
If you want to see how this looks in practice, the Poofora home page has screenshots from the app. Poofora is coming soon to the App Store. Scanning and reviewing are free, and the free plan includes a number of free deletions to begin with.
