Similar photos on iPhone: how to pick the keeper
The Photos app can merge exact duplicates for you, but a run of near-identical shots, such as a Burst or ten tries at the same group photo, is your call. Here’s how to tell the two apart, and how to pick the one to keep without agonising over every frame.
Duplicates and similar photos are two different problems
They look alike in a camera roll, but they need different tools.
| Duplicates | Similar photos | |
|---|---|---|
| What they are | Copies of the same photo or video | Separate shots taken moments apart |
| Typical example | The same image saved more than once | A Burst, a retaken group photo, five tries at a sunset |
| Who decides | Photos finds them and can merge them | You: each shot is slightly different |
| Built-in tool | Duplicates album (iOS 16, iPadOS 16.1 and later) | Burst selection for Bursts; otherwise, your own eye |
Start with duplicates, because they need no judgment, then spend your attention on the similar shots.
Exact copies: merge them in the Duplicates album
The Photos app looks for duplicate photos and videos in your library and collects them in a Duplicates album. Detection happens automatically and can take some time, and if you have no duplicates, the album doesn’t appear.
- Open Photos and tap Collections.
- Under Utilities, tap Duplicates.
- Tap Merge on a set of duplicates, then tap Merge [number] Items to confirm.
- To merge several sets at once, tap Select, tap Select on each set (or Select All), then tap Merge.
According to Apple, merging combines the highest image quality and relevant data to keep one photo in your library, and the other copies move to Recently Deleted. Because the extra copies go to Recently Deleted, you can still recover them for 30 days if a merge surprises you.
Apple describes this album as finding duplicates. It doesn’t say it groups shots that are merely similar, so don’t count on it to clear your Bursts and retakes.
Bursts: start from the suggested frames
Burst mode takes a rapid series of photos so you have a range to choose from. Apple’s Camera guide describes how to pick the ones to keep:
- Tap the Burst thumbnail, then tap Burst (number).
- Gray dots below the thumbnails mark the photos suggested to keep.
- Tap the circle in the lower-right corner of each photo you want to save as an individual photo, then tap Done.
To get rid of the whole Burst instead, tap its thumbnail, then tap the Trash button.
The gray dots are a good starting point, not a verdict. Check the suggested frames with the questions in the next section before you tap Done.
How to choose the keeper in a run of similar shots
For everything that isn’t a duplicate or a Burst (retakes, slightly different angles, the same view at three zoom levels), the choice is yours. A short, fixed checklist keeps it quick:
- Faces first. Zoom in on eyes and expressions. A slightly softer photo where everyone looks good beats a sharp one with someone blinking.
- Then focus and blur. Is the subject sharp? Is there motion blur on the part that matters?
- Then the edges. Cut-off heads, a tilted horizon, a stranger walking through, a thumb in the corner.
- Group photos: count the people. The keeper is the one where everyone is in the frame and looking roughly the right way.
- Keep one, or two at most. If two shots tell different stories, a wide one and a close-up, keeping both is fine.
Give each group a few seconds. If you can’t decide, keep both and move on; the next time you look, the better one is usually obvious. Speed is the point here: the cost of keeping one extra near-duplicate is small, while agonising over every group is how cleanups stall.
When you’ve chosen, delete the rest the usual way: tap Select, tap the photos you don’t want, then tap the Trash button. They move to Recently Deleted for 30 days.
A routine for a big trip
After a trip, work by day rather than scrolling the whole album. Start with the day you took the most photos, go through it group by group with the checklist above, and stop when the day is done. One day per sitting keeps every decision fresh, and you can see the album shrink as you go.
Where SnapTidy helps
The slowest part of this is finding the runs of similar shots in a big library and comparing them side by side. That’s the part SnapTidy takes on.
In short
- Duplicates are copies; similar photos are separate shots. They need different tools.
- Merge copies in Photos › Collections › Utilities › Duplicates. Photos combines the highest image quality and relevant data into one photo and moves the rest to Recently Deleted.
- For a Burst, start from the frames marked with gray dots, then check them yourself.
- For other similar shots: faces, then focus, then edges. Keep one, two at most, and move on.
