Hi, this is Gary with MacMost.com. Let me show you how you can detect
and delete duplicate photos in the Photos App on iOS 16.

So a new feature in iOS 16 is the ability to see duplicate photos
in the Photos App and then choose what to do with them, like merge them or delete one or the other.
Here's how it works. First, Apple puts this function in the Album section. So you're going
to go down to the bottom and tap on Album. You're going to see all your albums there. Shared Albums,
People, Places, different things like that. Media Types and at the very bottom you're
going to see Utilities. One of those utilities is Duplicates. It will show you the number of
duplicates it has found right there. Now, if you don't see a Duplicates Folder there?
The reason probably is you simply don't have any duplicates. The Photos app hasn't found any photos
that qualify to being duplicates. Therefore no Duplicates Folder will be shown under Utilities.
Now it finds them in the background. So this isn't something that works when you actually tap
Duplicates. It's finding duplicates all the time. It may take some time if you have a
large photo library and you've just updated to iOS 16 or maybe you've just added a lot
of photos. So something happens in the background and it may take a little while
after you add new photos or update. Also probably depends on how big your library is.
Now when you tap on Duplicates then you're going to into this special album. It's a list of
all the photos that have been found that the Photos App thinks are duplicates. So it is finding
photos that are identical. They are exactly the same photo taken exactly the same time,
exactly the same bits in the photo. But it is also finding photos that might differ in some
ways. For instance a photo may be a different resolution. Like maybe you exported from Photos.
Edited it and resized it in another app and brought it back into Photos. So now you have
two identical photos but different resolutions. If may also find photos that are nearly identical.
Maybe ones you took just one second after the other so they look extremely similar.
So you can look through the list here. You can see I even have one that is there three
times. So I can go through and browse through this like it is kind of an album and see the
different duplicates. I can tap on one and then go down into the pair. I can swipe between them
and see each one. I can also tap at the bottom to switch between them which does it without
the animation between them so it may be a better way to see if they are actually identical or not.
Take a look at this last one here. It's actually two different photos. I just pointed the iPhone
down at the ground under my desk and took two photos and they are extremely similar. It's
hard to tell the difference. But if you look closely you can see that they actually were
taken at different times. This, of course, is my special photo collection for making
tutorials. But in my regular photos collection I actually have photos where there are people in
them and you can see they are different photos. They are slight differences in the background
or in the positions of people. It's very close but they are definitely not exactly
the same photo. Still I may not want to have both photos in my library since they are so similar.
Now you can get rid of duplicate photos one of a few different ways. One way is just to go into
the pair and go between them and then the one you want to delete you use the Trash Can or
bin icon down here to get rid of it. Another thing you can do is just have the Merge button
next to the date for the photo. If they're identical, well, it really doesn't matter
which one is deleted. They're the same photo. So deleting one or the other is not going to
make any difference. So what exactly does Merge mean then in that context? Well, it's not always
about the photo because sometimes you've got data attached to the photo like, say, a caption or you
might have key word tags and other information. When you use Merge you will preserve that.
For instance, let's take a look at this one right here. Let's go in and you can see for the first
one there's no caption there. But if I swipe over to the second one you can see there is a caption.
So I created a caption and I didn't realize there was a duplicate. Now I have one without
a caption and one with a caption. So the idea is by merging those two it's going to preserve that
caption. It is going to make sure that the one and only one I have left has that caption. Let's
try that. I'll tap Merge and merge the two items. Notice that now it disappears from the Duplicates
Album because there is no longer a duplicate. There's only one of that photo. Now if I go to
my library and find that photo and then I go and look at it I'll notice the caption was preserved.
It's smart enough to make sure that caption now exists for that one and only copy of the photo.
Now back in Duplicates what if I had two duplicate photos and each has a different caption.
You could see here for the first photo I've got this caption. For the second
photo I have a different caption. So let me merge these two photos and see what happens.
I'll merge them. It disappears from here. Now when I go and find it in my library and take a look
at the resulting photo. I can see it took both captions and it put them, one on one line and one
on another. I didn't lose either caption. You could see here I've got a set of three and can
merge all three of these together and here's two I've got. Notice the sizes for these two.
They are different sizes. So one of them was taken out of Photos, resized and brought back in,
but this Duplicates Album recognized them as the same photo even though one has been resized. Now
if I merge these two what happens is it's going to be smart enough to take the higher resolution one.
So merging isn't somehow merging the pixels from one photo to another. I've already seen people
misunderstand it that way. It's only going to take one of the photos. It's not going to do any kind
of weird magic to try to merge two different photos to combine them. It's just taking the
highest resolution version of the two photos and then merging the data between them like captions.
Now here's another thing. If we go back here to Albums to the Utilities section there is
Recently Deleted. If we go into Recently Deleted notice that when we merge photos one of them gets
deleted. That deleted photo goes into Recently Deleted. So it's doing the right thing here. It's
not getting rid of it and not allowing you any recourse to get it back. It's actually putting
it here where it will sit there for 30 days. So if you did make a mistake in merging two photos
that weren't the same or something like that then you can go to Recently Deleted and find it.
So this utility in Photos is actually doing exactly what I've suggested over the years
every time somebody has asked me how do you get rid of duplicate photos. That's to compare
your photo side-by-side. Figure out what's going on and delete the one that you don't
want or if they are identical just delete either one. Don't let an automatic process
just delete photos for you. Photos are too valuable to have an automatic process perhaps
make a mistake. This utility puts those duplicates side-by-side rather than having
you scroll through all of your photos. So it makes the process a little easier. It also makes it very
easy to merge any data in case you did put a caption on one and some other data on another,
you don't have to manually take care of that when getting rid of duplicates.
Now the same feature is coming to macOS Ventura. So unless you only have an iPhone I would wait
and do this process on your Mac where you have a bigger screen and it is easier to see what
is going on and work with it using the Keyboard, or Trackpad, or Mouse. Since iCloud Photos works
across all your devices it doesn't matter which one you do it on if you are using iCloud Photos.
This won't get rid of the root problem of why you have duplicate photos. Maybe you just
have a few created by a few simple mistakes over the years. But if you constantly have
duplicate photos you have to figure out why. Maybe you're doing something like using both
iCloud Photos but you're still connecting a cable and manually sneaking photos.
Maybe you're overriding the duplicate detection when you import photos. Maybe you're using some
sort of third party app to edit the photos and it is creating a copy every time it does that.
It's important to figure out what's going on if duplicate photos are a persistent problem for you.
Fix that problem or change your behavior so this doesn't become a common occurrence.
But at least now when somebody does have existing duplicate photos instead of trying
to figure out how to compare them and get rid of them there's an easy function inside
the Photos App that they can go to to do that. Hope you found this useful. Thanks for watching.
