How does Google photo deal with duplicates?

Use Identical Duplicate Detection With Google Photos

Google does try to prevent exact duplicates with an “identical duplicate detection” feature. This will scan the contents and metadata of any image you upload to the cloud and check to make sure you haven't already uploaded it.

Does Google photo duplicate?

Google Photos tries to avoid exact duplicates, but does not always succeed when different upload methods or devices are used. Also photos which have been edited or metadata changed may be uploaded again. A different title/path does not trigger a new upload.

How do I search for duplicates in Google Photos?

In some cases, you may see duplicates in the Google Photos app on your phone, but they don't really exist. To check out if photos are really duplicated in Google Photos, go to https://photos.google.com/, sign in with the same account used in the app and see if duplicates show up there.

Why are my Google Photos doubled?

One of the reasons why there are duplicate photos in Google Photos is because there are duplicate photos on the device. In order to get the best one, you will try to take multiple shots, which will result in many duplicate photos and those duplicate photos will upload to Google Photos.
