Having a lot of duplicate photos in your Photos library on your Mac can be frustrating. It takes up valuable storage space and makes it harder to find the images you’re looking for. Fortunately, there are several ways to tackle this issue and reclaim control over your photo collection. At dfphoto.net, we’re dedicated to helping you manage your photography effectively, so let’s dive into the best methods for removing those pesky duplicates, ensuring your photo library remains organized and efficient.
1. Why Do Duplicate Photos Happen on Mac?
Duplicate photos can accumulate on your Mac for various reasons. Understanding these causes can help you prevent future occurrences.
- iCloud Sync Issues: Sometimes, glitches during iCloud synchronization can lead to photos being duplicated across devices.
- Importing Photos Multiple Times: Accidentally importing the same photos from your camera, phone, or external drive more than once is a common culprit.
- Software Bugs: Bugs in the Photos app or macOS can occasionally cause duplication issues.
- Backups: Restoring from backups can reintroduce older versions of photos already in your library.
- File Conversions: Converting photos to different formats (like JPEG to HEIC) can sometimes create duplicates if the originals aren’t deleted.
2. What are the Implications of Duplicate Photos?
Duplicate photos might seem like a minor issue, but they can have several negative implications:
- Storage Space: Duplicates consume significant storage space on your Mac and in iCloud, especially with high-resolution images.
- Organization: They clutter your photo library, making it harder to find the photos you need quickly.
- Backup Time: Backing up your photo library takes longer and requires more storage space due to unnecessary duplicates.
- Performance: A large, disorganized photo library can slow down the Photos app and your Mac in general.
3. Using the Built-in “Merge Duplicates” Feature in Photos
MacOS Ventura and later versions offer a built-in “Merge Duplicates” feature in the Photos app, making it easier to identify and remove duplicates.
How to Use Merge Duplicates
- Open Photos: Launch the Photos app on your Mac.
- Check the Sidebar: Look for the “Duplicates” option in the sidebar. If you don’t see it, Photos may still be analyzing your library. Give it some time, especially if you have a large collection.
- Review Duplicates: Click on “Duplicates” to see groups of photos that Photos believes are duplicates.
- Merge or Skip: For each group, you can either click “Merge” to combine the duplicates into a single photo or click “Skip” if you want to keep them separate.
- Confirm: After merging, Photos will move the duplicates to the “Recently Deleted” album, where they will be permanently deleted after 30 days unless you manually delete them sooner.

Pros of Using Merge Duplicates
- Convenience: It’s built right into the Photos app, so you don’t need to download any additional software.
- Easy to Use: The interface is straightforward and easy to understand.
- Free: No extra cost is involved.
Cons of Using Merge Duplicates
- Potential for Errors: The “Merge Duplicates” feature isn’t perfect and can sometimes make mistakes, like deleting the higher-quality version of a photo.
- Lack of Control: You have limited control over which version of a photo is kept. Photos typically keeps the newest version, which may not always be the best.
- Time-Consuming: Reviewing and merging duplicates can be time-consuming, especially for large libraries.
4. Cautionary Tales and Tips for Using Merge Duplicates Safely
While the “Merge Duplicates” feature is convenient, it’s essential to use it with caution to avoid losing valuable photos.
Back Up Your Library First
Before using the “Merge Duplicates” feature, back up your entire Photos library. This ensures you can restore your photos if something goes wrong. You can back up to an external drive or use Time Machine.
Double-Check Before Merging
Carefully review each group of duplicates before merging. Make sure you’re keeping the version you want and deleting the correct duplicates. Pay attention to:
- File Size: Larger file sizes usually indicate higher quality.
- Resolution: Ensure the photo you’re keeping has the highest resolution.
- Date: If you’ve back-dated any photos, be aware that Photos may keep the newest version regardless of quality.
Consider Third-Party Software
If you’re uncomfortable with the limitations of the built-in feature, consider using third-party software designed specifically for finding and removing duplicate photos.
5. Third-Party Software for Deleting Duplicate Photos

8. Preventing Duplicate Photos in the Future
Preventing duplicate photos from accumulating in the first place is the best way to keep your photo library organized. Here are some tips:

9. Understanding “Higher Quality” in Photos
Apple claims that the “Merge Duplicates” feature preserves the “higher quality” version of a photo. However, what does Apple mean by “higher quality”? According to discussions with Apple support representatives and community observations, here are some factors that may influence Apple’s determination of quality:
- Resolution: Photos typically prioritizes photos with higher resolution (more pixels).
- File Format: HEIC format may be favored over JPEG due to its more efficient compression.
- File Size: Larger file sizes may indicate higher quality, but this isn’t always the case, as compression can affect file size.
- Editing History: Photos may consider the editing history of a photo when determining quality.
- Metadata: Other metadata, such as color profiles and bit depth, may also play a role.
However, it’s important to note that Apple’s definition of “higher quality” isn’t always clear-cut, and the “Merge Duplicates” feature can sometimes make questionable decisions. That’s why it’s crucial to review the duplicates carefully before merging them.
10. The Importance of Backups
Regularly backing up your photo library is essential for protecting your precious memories. Here’s why backups are so important:
- Data Loss: Hard drive failures, accidental deletions, and other unforeseen events can lead to data loss. Backups ensure you can recover your photos in such cases.
- Disasters: Fires, floods, and other disasters can destroy your computer and your photos. Offsite backups protect your data from physical damage.
- Software Issues: Bugs in the Photos app or macOS can sometimes corrupt your photo library. Backups allow you to restore your library to a previous state.
Backup Options
- Time Machine: macOS’s built-in backup utility. It automatically backs up your entire system to an external drive.
- iCloud Photo Library: Syncs your photos to the cloud, providing a backup in case of local data loss.
- External Hard Drive: Manually copy your photo library to an external hard drive for safekeeping.
- Cloud Storage Services: Use services like Google Photos, Dropbox, or OneDrive to back up your photos to the cloud.
