Tired of scrolling through duplicate photos in Google Photos? Our guide reveals 4 free methods to clean up duplicates and 3 smart tips to stop them from coming back. Reclaim your storage and enjoy a clutter-free photo library.
Content Overview:
I am collecting photos from family for someone's funeral. The problem is that a lot of photos I'm being sent are duplicates and it's too many photos to keep track of on my own. I've added all of the photos from my computer to an album on Google Photos, but the duplicates are still there.
I cannot find a single article or Reddit post detailing how to remove the duplicate photos with Google Photos that doesn't involve 3rd party software. iOS automatically finds duplicates and merges them "intelligently" (using the higher quality dupes), so why can't Google Photos?
Maybe I'm just stupid and not seeing the option anywhere?
- Question from https://www.reddit.com/r/googlephotos
I have multiple duplicates of many photos. The manual process is insane. How do I delete duplicate photos from Google Photos automatically? It's awful that there's no easy way to do this. I've spent countless hours and still haven't found a way, and I've done some work manually but I've barely put a dent in my collection.

To effectively find and remove duplicate photos in Google Photos, we first need to understand their origin. Let's examine the common causes behind duplicate uploads.
Google Photos has built-in "identical duplicate detection", but that doesn't mean it always avoids duplicates. Understanding how it works is the key to solving the problem.
The Hash-Based Detection Process
Every photo you upload has a unique "hash" value —a digital fingerprint that identifies the file. When you upload a photo to Google Photos:
While hash-matching is effective for exact duplicates , it has one major blind spot: any modification changes the hash — even a single pixel edit, format conversion (PEG ↔ PNG), or metadata change creates a completely new hash, causing Google Photos to treat it as a different file.
This explains why you might still see similar photos in your library even though Google Photos has "duplicate detection."
While Google Photos' hash-based detection system works well for exact duplicates, several other factors can cause duplicates to slip through.
One of the most frequent culprits behind duplicate photos is the use of discontinued or legacy upload tools. Older applications like Picasa, the original Desktop Uploader, and early versions of Backup and Sync handled file metadata differently than modern Google Photos.
When these legacy tools uploaded photos, they often modified the file's metadata during the process. Later, when you use current Google Photos tools to upload the same images, the modified metadata creates a different hash value, causing the system to treat them as entirely new files. This creates a frustrating cycle where the same photos keep reappearing in your library despite your best efforts to organize them.
Uploading photos from multiple devices introduces another significant source of duplicates, with video files being especially vulnerable to this problem.
While photos uploaded from different devices like phones, computers, or network-attached storage systems generally avoid duplication due to consistent hash calculation, videos behave differently. The same video file uploaded from your phone and later from your computer will often result in two separate copies in your Google Photos library.
This discrepancy between photo and video handling stems from how different devices process and encode video metadata, leading to hash variations even when the visual content is identical.
Major changes to your digital environment can trigger widespread duplicate generation. When you acquire a new phone, purchase a new computer, reinstall your operating system, or upgrade your backup application, Google Photos treats these as entirely new upload sources.
The service rescans your entire photo collection and re-uploads historical photos because it cannot establish continuity between your old device configuration and the new one. This scenario is particularly problematic during phone upgrades, where users expect a seamless transition but instead find their entire photo history duplicated in the cloud.
User's dilemma
A Samsung user factory reset their phone and reinstalled Android. After copying photos back to the original folder, Google Photos treated 2,000+ identical photos as new uploads — forcing the user to disable sync to avoid duplicates.

Professional photographers and enthusiasts who use cameras with RAW shooting capabilities often encounter duplicates due to dual-format recording settings. Many high-end cameras are configured by default to save both RAW and JPEG versions of every shot simultaneously.
Since these are technically different file formats with distinct structures, Google Photos treats them as separate files rather than versions of the same image. The result is pairs of photos that look identical in your library but occupy twice the storage space. Disabling dual-format recording in your camera settings can prevent this issue at the source.
The integration between Google Drive and Google Photos, while designed for convenience, can inadvertently create duplicates.
When the sync feature between these services is enabled, photos stored in Google Drive automatically appear in Google Photos. If you subsequently upload the same photos directly to Google Photos through the app or website, you end up with two copies of each image.
This duplication occurs because the synced version from Drive and the manually uploaded version are treated as separate entities within the Google Photos system.
Occasional technical problems can also contribute to duplicate creation. Network interruptions during upload may cause the system to retry failed transfers, resulting in multiple copies. Application bugs in Google Photos, though rare, can cause sync errors. Additionally, rapidly switching between multiple Google accounts on the same device can confuse the synchronization process and lead to duplicate uploads.
Many users are unwilling to remove duplicates in Google Photos manually due to time-wasting. Unfortunately, there are only manual ways until now.
Note: No matter which way you take below, bear in mind that the Google Photos backup app does not perform a sync function from cloud to local. Otherwise, when you delete duplicates, your local source photos may be deleted at the same time.
In the following parts, you will find 4 ways to help remove duplicate photos from Google Photos.
If the number of duplicate photos is not too much, you can try to delete these duplicates manually.
1. Log in to Google Photos official website.
2. Click on "Photos" in the left panel.
3. Find these duplicates, select photos that you don't need, and click on the "Delete" option.
Google Photos can prevent some exact duplicate uploads automatically. When you upload a file, Google Photos may compare its file signature and metadata with existing items in your library. If the file is considered identical, the upload may be skipped automatically. However, edited versions, re-encoded videos, or files with modified metadata can still be uploaded as separate copies.
If duplicate photos were uploaded at different times, it may be easier to identify and remove them through the “Recently added” view in Google Photos Search (https://photos.google.com/search/_tra_). Items are generally sorted by upload date, allowing you to select photos in batches for review and deletion.
Tip:
While Google Photos offers basic duplicate detection, third-party tools provide more powerful solutions for identifying and removing duplicates—especially for "near duplicates" that Google might miss. One of the most popular tools is Google Photos Duplicate Remover, a Chrome extension designed specifically for this purpose.
Step 1. Open the Chrome Web Store, search for "Google Photos Duplicate Remover" and click "Add to Chrome" to install the extension.
Step 2. Go to photos.google.com and sign in to your account. Click the extension icon in your Chrome toolbar. Select "Scan for Duplicates"- The tool will analyze your library and group identical/similar photos together.
Step 3. The extension will display duplicate groups and you can click the circle on the target photos to mark it for deletion.
Step 4. Once confirmation, marked photos will be moved to Google Photos’ trash folder.
Except for removing duplicate photos from Google Photos, you have another 3 tips for you to avoid duplicate photos in Google Photos:
Considering the causes of Google Photos upload duplicates, to avoid future Google Photos auto backup duplicates, users should:
Just open Google Photos and upload new local photos by dragging and dropping or "Import Photos" button.
Since the troubles Google Photos has given you, if you are fed up with it, you can switch to other cloud drive services like Dropbox and OneDrive. They have their own file backup tool to upload local files to cloud storage.
Or, you can make use of third-party software that enables you to upload local items to cloud tasks such as MultCloud. MultCloud, as a FREE online multiple cloud storage manager, can help you not only upload local files (of course including photos/videos) to its supported clouds (around 40) like Google Drive, Google Photos, OneDrive, iCloud, Dropbox, etc., but also remote upload to Google Drive.
3. Google Photos will be listed on the left side, then open a folder to store your photos and videos, then tap the Upload File from the top menu.
4. Select the photos and videos to upload photos to Google Photos without duplicates.
MultCloud also allows you to transfer/sync files among cloud drives directly as long as you add your clouds to MultCloud without using laborious uploading and downloading methods. For instance, sync pictures between OneDrive and Google Photos.
Following any way above can help you delete duplicate photos in Google Photos. This article not only guides you on how to remove duplicates in Google albums but also provides free ways to avoid Google Photos duplicates generating. In general, it is very useful for us to manage photos stored in Google Photos.
Many users have given their opinions about how to remove duplicates from Google Photos. They insist that Google should implement an ACTUAL duplicate detection to detect duplicated photos. When a photo is being uploaded but Google Photos finds it's the same as one of the photos uploaded previously, the Google Photos app will ask the user to decide whether to keep/merge (keeping the largest/most recent photo) or delete all duplicates.
If there are already duplicates in the cloud, Google Photos should give a function to search out all duplicates and delete them. This actual duplicate detection can detect files of the same content but in different file names, different upload dates, uploads by different clients, uploads from different local devices, etc. If you resolve the Google Photos duplicated photos, you can also move OneDrive Photos to Google Photos if you like.
