Does Google Photos Detect Duplicates?
The Difference Between Duplicates and Duplicate Images
Google Photos is a popular photo storage and sharing service that allows users to store, organize, and share their photos and videos. With its advanced features, such as automatic organization, hashtag suggestions, and improved search, Google Photos has become an essential tool for photographers and non-photographers alike. However, when it comes to detecting duplicates in Google Photos, users often wonder whether their photos are being automatically detected and removed.
What are Duplicates?
Before we dive into the question of whether Google Photos detects duplicates, let’s clarify what duplicates mean. Duplicates refer to identical or very similar photos, such as two identical images of a family vacation or two photos of the same mountain landscape. In Google Photos, duplicates are automatically detected and removed when you enable the "Keep best photos" feature.
How Does Google Photos Detect Duplicates?
To understand how Google Photos detects duplicates, let’s go through the process of creating and adding photos to your Google Photos account.
- Adding Photos to Google Photos
When you take a new photo or video, it’s added to your Google Photos account. If you don’t enable the "Keep best photos" feature, duplicates will not be detected.
- Enabling the "Keep best photos" Feature
To enable the "Keep best photos" feature, follow these steps:
- Go to your Google Photos account page
- Click on the three vertical dots next to your account name
- Select "Settings"
- Click on "Account Settings"
- Scroll down to the "Delete excess photos" section
- Select "Keep best photos"
- Click on "Save changes"
With this feature enabled, Google Photos will automatically detect and remove duplicates.
How Google Photos Determines Duplicates
When Google Photos detects duplicates, it uses a complex algorithm to determine whether two photos are identical or very similar. The algorithm takes into account factors such as:
- Image resolution: If two photos have the same resolution, but are different orientations or colors, it’s likely that they are duplicates.
- Color palette: If two photos have the same color palette, but are different shades of the same color, it’s likely that they are duplicates.
- Image compression: If two photos have the same image compression, but are different sizes, it’s likely that they are duplicates.
What If I Don’t Enable the "Keep best photos" Feature?
If you don’t enable the "Keep best photos" feature, duplicates will not be detected. In fact, Google Photos will simply display a list of duplicate photos and allow you to delete them manually.
How to Remove Duplicate Photos Manually
To remove duplicate photos manually, follow these steps:
- Select the photos you want to delete
- Click on the three vertical dots next to the photo
- Select "Delete photo"
- Confirm that you want to delete the photo

Important Notes
- Duplicates are not removed by default: If you don’t enable the "Keep best photos" feature, duplicates will not be detected and removed automatically.
- Duplicates can be deleted manually: If you don’t enable the "Keep best photos" feature, duplicates can be deleted manually by selecting them and clicking on the "Delete photo" option.
- Google Photos stores duplicates for 30 days: After 30 days, duplicates are removed, but you can still delete them manually.
Conclusion
Google Photos is designed to automatically detect and remove duplicates, ensuring that your photos are organized and easily accessible. By enabling the "Keep best photos" feature, you can ensure that duplicates are removed and your photos are only stored in your Google Photos account. If you don’t enable the feature, duplicates will not be detected, and you’ll need to delete them manually.
