Identify Similar Photos on iPhone Without Duplicates

Duplicate vs. Similar Images

It’s important to understand that duplicates and similar images are not the same. Since iOS 16, Apple’s Photos app can detect duplicates based on exact file characteristics—like metadata and pixel data—but similar images may look nearly identical to the human eye while remaining technically unique. These won’t show up in Apple’s built-in duplicate detection.

What Counts as a Duplicate?

Apple considers a photo a duplicate if it matches another file in these ways:

  • Exact pixel data: The image must be a bit-for-bit match. Even small edits, like cropping or brightness adjustments, create a new unique file.

  • Identical metadata: The timestamp, resolution, format, and camera settings must match. Any minor difference, such as a slight exposure change, makes the image unique.

  • Matching file hash: Photos likely use a cryptographic hash (like SHA-256) to compare files. Identical hashes mean the system treats them as duplicates.

Note: Photos that look almost identical but differ slightly—different angles, lighting changes, or motion variations—won’t be flagged as duplicates. For these, you’ll need additional tools or strategies.


3 Ways to Find Similar Photos on iPhone

Now let’s cover how to manage similar photos that Apple’s built-in tools ignore. We’ll start with the easiest, fastest method and then look at hands-on alternatives.

Method 1: Use a Third-Party App

The simplest and most effective solution is a third-party app designed to detect visually similar images. Unlike Apple’s Duplicates album, these apps can find photos that look alike but aren’t exact copies.

We’ve tested dozens of these tools and recommend checking our rating of the best apps to remove duplicate photos on iPhone.

For demonstration, we’ll use Clever Cleaner: AI Cleaner, ranked #1 in our review. Key points about this app:

  • Completely free with no hidden payments or ads.

  • Uses powerful AI to detect similar and exact duplicates, rivaling premium apps on the market.

  • Simple, intuitive interface, with options for automatic or semi-automatic cleanup.

Here’s a quick guide to get started with Clever Cleaner:

You can either type “Clever Cleaner” into the search bar in the App Store or download it using this link.

  1. Open the app and go to the Similars tab.

  2. At the bottom, tap Smart Cleanup. The app will scan your library in seconds and suggest images for deletion.

  3. If you don’t want to remove a specific photo, tap Restore to keep it.

  4. Scroll through the list and review the choices. If you approve, Slide to delete, confirm the deletion once more and the app will take care of the rest.

  5. Alternatively, if you want to go through each group for a more hands-on cleanup, tap on a group and make decisions on your own.

  6. The app’s AI automatically preselects the Best Shot to keep. It is quite good at this, but if you disagree, you can choose a different shot.

  7. When you made your decision tap Move to Trash to delete the marked photos or Skip All to skip this group and move to the next one. This process is fast and definitely easier than manually sorting in the Photos app.

  8. When finished, tap Empty Trash at the bottom. The app will ask for confirmation before deletion.

Note: Clever Cleaner follows Apple’s standard behavior for deleted media. All photos you remove—including similar images—will remain in the Recently Deleted album in the Photos app for 30 days. If you want to free up space immediately, you can manually empty this folder so the deleted photos no longer occupy storage.

Beyond just finding similar photos, Clever Cleaner offers three additional tools to reclaim even more storage. Like the Similars tool, these features are completely free and unlimited, and according to the app’s official page, early users will retain free access indefinitely. Here’s a quick overview of what they do:

  • Screenshots – The app identifies all screenshots you have taken and allows you to delete them all in one go.

  • Lives – This feature converts Live Photos into still images, which reduces storage space without losing the core of the shot.

  • HeaviesSorts your videos by size from big to small for quick removal—something the Photos app can’t do natively.

Method 2: Use Built-in Photos App Features

If you prefer not to use third-party apps, the Photos app still offers a few helpful tools. While it can easily detect exact duplicates, finding similar images is more limited. Apple doesn’t provide a dedicated feature for this, but you can leverage the Albums and Search functionalities to group and manage similar photos. It’s not as fast or automatic as an AI-powered cleaner, but it can still help tidy up your library.

Use Albums to Group Similar Images

The Photos app automatically generates albums based on various criteria such as location, date, and photo type (e.g., Live Photos, Portraits, Panoramas). Browsing these albums can help you spot groups of visually similar images. Once grouped, you can quickly review them and delete duplicates or unnecessary shots manually.

  1. Open the Photos app and tap on the ‘Albums‘ tab at the bottom.

  2. Scroll to find albums automatically created by your iPhone, such as ‘Selfies‘ or ‘Landscapes.’

  3. Review these albums to discover groupings of similar images based on the context of the photos or the camera settings used.

Refine People & Pets Recognition

If Apple misses any faces in the People & Pets album, you can add them manually to improve future recognition:

  1. Open a photo.

  2. Tap the Info (i) button.

  3. Tap the person or pet with a question mark next to their image.

  4. Select Name This Person or Name This Pet.

Over time, this helps the Photos app better identify similar faces in your library.

Use Search to Find Images by Content

The Search tab in Photos leverages image recognition to categorize your photos by objects, scenes, and activities. It can detect thousands of items, such as:

  • Beaches, mountains, and landscapes

  • Pets and animals

  • Food, events, or landmarks

If you remember taking multiple photos of the same subject, entering keywords in Search can help locate similar images quickly.

Pro Tips:

  • Try combining keywords, like “dog + beach,” to narrow results.

  • Use dates or locations alongside keywords to find duplicates from specific trips or events.

  • Periodically review albums and search results to catch images that Apple might not automatically group.

  • You can combine search terms to narrow down results. For example, searching “dog New York” will show only photos of dogs taken in New York.

  • If you don’t find what you’re looking for, try a broader keyword. Searching “car” might return more results than “red Ferrari” since Apple’s algorithms may not recognize specific details.

  1. Tap on the ‘Search‘ icon in the Photos app.

  2. Enter a keyword like ‘beach,’ ‘dog,’ or ‘sunset.’ The app will display photos that match the descriptor, often pulling up similar images related by content.

  3. Browse through the results to find and organize images that are visually or contextually similar.

While albums and search help sort photos, they lack automation. If you manage your iPhone photos on a Mac, there’s another way to organize similar images faster: Smart Albums. The next section explains how to use them.

Did You Know?
The Photos app’s search functionality has come a long way. Initially, it could only recognize simple objects and scenes, but now it can identify a wide range of subjects and even suggest memories based on people, places, or events. With iOS 18, Apple Intelligence (AI) further improves search accuracy, recognizes more complex subjects, and generates smarter suggestions.


Method 3: Create Smart Albums on a Mac

If you manage your photos on a Mac, Smart Albums offer a faster and more automated way to organize similar images. Unlike the iPhone Photos app, which requires manual sorting, Smart Albums can automatically group photos based on rules you set.

Key Advantages:

  • Automation: Automatically groups photos by criteria you define.

  • Advanced Filtering: Use metadata such as date, file size, file type, or keywords.

  • Bulk Actions: Quickly select and delete or move large numbers of photos—no need to tap each image individually.

Step-by-Step Guide:

  1. Open the Photos app on your Mac.

  2. Go to File > New Smart Album.

  3. Name your Smart Album and set rules, e.g.,

    • Date captured

    • Photo type (Live Photo, screenshot, burst, etc.)

    • File size

    • Keywords or descriptions

  4. Click OK to create the album.

  5. Review the grouped photos and take action—delete, move, or tag as needed.

Smart Albums are perfect for large libraries and can save hours compared to manually sorting photos on an iPhone.

Here’s a simple guide on how to use this feature:

  1. Connect your iPhone to your Mac and sync your photos. This can be done using Finder on macOS Catalina and later, or iTunes on earlier versions. (You can also use iCloud Photos to sync albums on both of your devices.)

  2. Open the Photos app on your Mac, go to ‘File‘ > ‘New Smart Album‘. Set criteria like date, camera type, or keywords such as “holiday” or “family”.

  3. Smart Albums automatically update when new photos that meet the criteria are added. This keeps your photos organized without ongoing effort.

Smart Albums on Mac vs. Third-Party Apps

While Smart Albums on a Mac don’t analyze the actual image content like AI-powered third-party apps do, they provide a faster, more organized way to sort and delete similar photos compared to the iPhone’s Photos app. If your photos are synced with iCloud, using Smart Albums can save significant time when performing bulk deletions. For those who prefer a structured, manual approach, this method works well—but for true automation, a third-party app remains the most efficient choice.


Final Words

Thanks to AI, finding and removing similar photos on an iPhone has never been easier. Tools like Clever Cleaner automatically group images, suggest which photo to keep in each set, and perform cleanup in seconds—a task that used to take hours of manual sorting.

If you can’t or prefer not to use third-party apps, the built-in Photos app still offers some helpful features. As of iOS 18, it can organize images by categories like Recent Days, Trips, and People & Pets. It’s more basic than dedicated tools, but Apple continues to improve these features with every update.

For Mac users, the Photos app on macOS adds even more options. Smart Albums allow you to automatically group photos based on metadata such as date, file size, or keywords, making it easier to organize and delete similar images in bulk. Managing your library on a larger screen also gives a clearer overview when sorting hundreds or thousands of photos.

Whether you prefer AI-powered automation, built-in Apple tools, or a Mac-based approach, there’s a solution to fit every workflow and help keep your iPhone or Mac photo library clean and organized.
