How to delete similar photos and burst shots quickly

You take six photos to be sure one is good. That is sensible. The problem is that all six stay on the phone, and after a few years the look-alikes outnumber the photos you would ever show anyone. This guide covers the quickest ways to keep the best shot and remove the rest, on iPhone and on Android.

Duplicates and similar photos are different things

A duplicate is the same file twice. Phones can find those with certainty, and the iPhone has a built-in album for them. See how to delete duplicate photos on iPhone.

Similar photos are different pictures of the same moment: the same pose a second apart, a burst of a child running, three attempts at a sunset. No tool can decide for you which one is best, but a good one can put them next to each other so that the decision takes two seconds.

Clean up burst shots on iPhone

A burst is saved as one item that holds many frames, so one burst can hide dozens of photos.

Open Photos and scroll to Media Types, then tap Bursts.
Open a burst and tap the control that shows all its frames. Depending on your iOS version it is labelled Burst or Select.
Swipe through the frames and tick the ones you want to keep.
Tap Done, then choose to keep only the frames you ticked.

The frames you picked become normal photos and the others are deleted. If the Bursts album is not there, you have no bursts in your library.

Clean up similar shots by hand in Photos

For ordinary look-alikes there is no dedicated album on iPhone, but the manual method is quicker than it sounds:

Open the first photo of the set and swipe through the set once.
Tap the heart on the one or two you like best.
Go back to the grid, tap Select, and drag your finger across the whole set.
Tap the photos with a heart to deselect them, then delete the others.

The heart does two jobs. It marks the keeper so you do not delete it by mistake, and it adds the photo to your Favourites album, which over time becomes the short version of your library.

On Android

Google Photos can group photos taken close together into a photo stack, shown as a single thumbnail. Open the stack to see every shot in it, choose the one you want on top, and remove the ones you do not need. The exact names of the options change between versions of the app, so look in the menu of an open stack.

Files by Google also helps. Its Clean tab suggests duplicate files and other items that are safe to review, and nothing is deleted until you select it and confirm.

How to pick the keeper in two seconds

Most of the time lost on similar photos goes on deliberating. A few rules make it fast:

Faces first. Eyes open and a natural expression beat everything else.
Then sharpness. Zoom in once. If the subject is soft, it goes.
Then framing. Nothing important cut off, horizon roughly level.
Keep one, or two at most. If two are equally good, keep the first and move on. You will not miss the other.
When in real doubt, keep it. The aim is to remove the obvious extras, not to agonise over the close calls.

Use a tool that groups them for you

The slow part of the manual method is finding the sets. An app can do that part. In Cleanup: Swipe Photo Cleaner, the Find Similar Photos tool groups look-alike photos together so you can choose the ones worth keeping, and Find Duplicates does the same for identical copies. You compare each group, pick, and confirm. Nothing is deleted until you do.

For everything that is not part of a set, the same app lets you go through one month at a time: swipe right to keep, left to delete, and undo if you change your mind.

Empty the trash when you are done

Deleted photos are not gone straight away. On iPhone they sit in Recently Deleted for up to 30 days. On Android they go to the trash or bin of the app you deleted them in, usually for 30 to 60 days. They take up space until then. When you are sure, empty it. This is the step that actually gives you the storage back, and it cannot be undone.

Keep the pile from growing back

Delete on the spot. Right after taking a set of photos, open the camera roll and remove the misses. It takes ten seconds while you still remember which one you liked.
Use bursts on purpose. They are useful for action and wasteful for everything else.
Set a small routine. A short session each week keeps similar photos from piling up. Our 10 minutes a day plan shows one way to do it.

Similar photos are the largest group of clutter in most libraries and the easiest to cut, because for every one you delete you still keep a better version of the same moment.
