How to Bulk Remove Duplicates from Google Photos 2021

Hundreds of millions of people use Google Photos to store their photos and videos. But it is easy to have duplicates of the same photos and videos in this storage service over time. It can take hours and even days to check and delete duplicates in Google Photos one by one by hand.

Right now, Google Photos doesn’t provide an official way to help you efficiently handle existing duplicates. Luckily, there are two workable methods that can help you safely remove duplicates from Google Photos, and here I’d like to show you each method with detailed steps.

Note: When looking for the available guides online, I find that some take Google Photos the same as Google Drive. But in fact, these two are totally different. Google Drive is a file storage service also developed by Google. And if what you want is to delete duplicate photos in Google Drive, please see this guide instead.

Before getting started: Check if the duplicate files really exist

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.

Method 1. How to bulk find and delete duplicates in Google Photos with software

Thanks to its duplicate detection feature, Google photos doesn’t allow exact duplicates. Exact duplicates are photos that are identical in every way regardless of filename.

The duplicates in Google Photos should be different (even very slightly) in file size or resolution or metadata.

There are a few online articles on easy ways to remove duplicates from Google Photos, but they are of little help. Being no expert on these matters, I finally figure out a non-manual method to do this.

Here’s how it works. Download all the files in your Google Photos to your computer, delete all the files from your account, use duplicate file finder software to find and delete duplicates, and then upload the duplicate-free photos and videos to Google Photos.

Note: But with this method, there are two disadvantages. You will lose the information (if any) you have added to your photos on Google Photos. Also, you will lose the albums (not the photos in it). In other words, you will need to manually recreate albums later.

If the photo information and albums don’t matter to you, then you can consider this method. The instructions below are broken into 2 parts. You can read through the instructions first and then decide if you want to use this method.

Tip: If needed, you can create a test Google account and test the method first.

Part 1. Download all files from Google Photos to computer

1. On your computer, sign in to Google.

2. Go to https://takeout.google.com/settings/takeout.

3. Click Deselect all.

8. Configure settings. Here I set it to download all my Google Photos items to a single ZIP file.

9. Click Create export.

When the data is ready to download, you will receive an email. Click Download your files. If there are gigabytes of files, it may take a while.

Now unzip the ZIP file. The unzipped folder will be automatically named Takeout. In the Takeout folder, you will find a folder called Google Photos. There, your Google Photos files are automatically organized into folders by year.

It’s recommended to keep the unzipped ZIP file as the backup of your Google Photos.

Now, delete all your photos and videos from your Google Photos account.

Google Photos duplicates FAQ

Does Google Photos upload duplicates?

Google Photos’ duplicate detection feature does a good job of preventing exact duplicates from being uploaded.

Exact duplicates are photos that are identical in every way (such as file size, resolution and metadata) regardless of filename. Metadata is the descriptive information attached to a photo and can include a description, a location, keywords, etc.

Supposed that photo "A.jpg" already exists in your Google Photos account. If you try to upload the same photo again to https://photos.google.com/, the upload will actually be ignored. But you won’t get a duplicate warning. If you copy photo "A.jpg" on your device and upload "A copy.jpg", it will be ignored too.

If you edit the metadata of "A.jpg" on your device and then upload it, Google Photos will recognize it as a different photo and upload it. As a result, there will be duplicates of photo "A.jpg" in your account. Google Photos will also upload compressed versions of photos despite them being visually the same.

Why is Google Photos duplicating my pictures?

You can access Google Photos by going to https://photos.google.com/. In addition, it has a dedicated app for Android and iOS. Google’s Backup and Sync desktop app also supports working with Google Photos.

You are allowed to set the Google Photos mobile app and the Backup and Sync desktop app to automatically back up photos from the selected folders/photo libraries on your device to the Google Photos service.

If Google Photos is duplicating all or some of your photos, it’s very likely related to the backup settings in one of the apps or both and multiple backups.


Conclusion

Google Photos doesn’t offer a built-in solution to easily deal with the existing duplicates. You can remove the unwanted duplicates manually or with the help of software. The two methods described above have their pros and cons. You can choose one based on your need. If you are not familiar with the type of software talked about above, you can get yourself familiar with the software by trying it with a test folder of photos.
