The Photo Library Problem

Every iPhone user knows the struggle. Your photo library grows endlessly with:

DiskCleanKit Dashboard
DiskCleanKit Dashboard
  • Burst shots - 10 photos of the same moment
  • Similar photos - Multiple attempts at the same shot
  • Blurry photos - Accidents you never deleted
  • Screenshots - Temporary captures you forgot about
  • Live Photo frames - Hidden duplicate images

How Much Space Are Photos Using?

Photo libraries commonly reach:

  • 20-50 GB for casual users
  • 50-100 GB for photo enthusiasts
  • 100+ GB for photographers

And often 20-40% of that is duplicates or similar photos!

DiskCleanKit's Similar Photos Feature

Our intelligent photo analysis goes beyond exact duplicates.

What We Detect

Exact Duplicates

  • Same photo saved multiple times
  • Photos imported from multiple sources
  • Backup copies

Similar Photos

  • Burst sequences
  • Multiple shots of the same scene
  • Photos with minor differences
  • Screenshots of similar content

Low Quality Photos

  • Blurry images
  • Dark or overexposed shots
  • Accidental captures

How It Works

Smart Analysis

DiskCleanKit uses advanced image comparison:

1. Visual similarity - Compares actual image content

2. Scene detection - Groups photos of the same moment

3. Quality scoring - Identifies the best shot in each group

Running a Photo Scan

1. Open DiskCleanKit

2. Go to Similar Photos

3. Select your Photos library or specific folders

4. Click Scan for Similar Photos

5. Review grouped results

Reviewing Your Photos

The Comparison View

Photos are grouped by similarity:

  • Group header shows number of similar photos
  • Best photo is automatically suggested
  • Side-by-side view for easy comparison

Selection Options

For each group, you can:

  • Keep best - Auto-select the highest quality photo
  • Keep all - Don't remove any from this group
  • Manual select - Choose exactly which to keep

What Makes the "Best" Photo?

DiskCleanKit considers:

Technical Quality

  • Sharpness and focus
  • Proper exposure
  • Resolution

Content Factors

  • Eyes open in portraits
  • Less motion blur
  • Better composition

File Attributes

  • Most recent edit
  • Highest resolution version
  • Original vs edited

Scanning Options

Full Library Scan

Scan your entire Photos library for the most thorough cleanup.

Folder-Specific

Target specific folders:

  • Downloads folder
  • Desktop screenshots
  • Imported photos folder

Date Range

Focus on specific time periods:

  • Last month's photos
  • Vacation photos
  • Event-specific cleanup

Screenshot Cleanup

Screenshots deserve special attention:

Common Screenshot Clutter

  • Address/directions screenshots
  • Social media saves

  • Similar screenshots (same app/website)

Safe Photo Cleaning

Preview Everything

Always preview before deleting:

  • View full-size photos
  • Compare side by side
  • Check for important differences

Photos Stay in Trash

Deleted photos go to your Recently Deleted album:

  • 30 days to recover
  • Review before permanent deletion
  • Peace of mind

What We Never Delete

  • Your only copy of a photo
  • Photos marked as favorites
  • Photos in albums (unless you choose)

After Cleaning

Verify Your Library

After cleanup:

1. Open Photos app

2. Browse recent photos

3. Check Recently Deleted if needed

Prevent Future Buildup

Take Fewer Burst Shots

  • Disable burst mode when not needed
  • Review and clean bursts immediately

Delete While Shooting

  • Review photos on your phone
  • Delete obvious bad shots immediately

Regular Maintenance

  • Monthly similar photo scans
  • Clean screenshots weekly

Results to Expect

Typical space savings:

  • 5-15 GB from similar photos
  • 1-5 GB from screenshots
  • 2-10 GB from exact duplicates

Your photo library will be cleaner, more organized, and much smaller!
