Peakto introduces powerful AI-driven tools to deduplicate and cull images across your entire library. Unlike traditional tools limited to a single folder or catalog, Peakto lets you run culling and deduplication globally, across collections, sources, external drives, and catalogs.

These tools help you quickly identify duplicate, near-duplicate, or similar images—and decide which ones to keep, flag, or remove.

Accessing the Culling & Deduplication Tool

1. Select the scope you want to work on:
   
   

• An entire library
  
  

• One or multiple collections
  
  

• A single source or a group of sources
  
  

2. Click the Deduplication & Culling icon (loop icon) in the left panel.
   
   

Peakto displays the number of images that will be analyzed before launching the process.

Choosing a Culling or Deduplication Template

Peakto provides templates that define how images are grouped and evaluated.

Deduplication

• Groups nearly identical images
  
  

• Ideal for removing exact or very close duplicates
  
  

Culling

• Groups similar images (bursts, variations, reshoots)
  
  

• Designed to help you select the best shots within a series
  
  

Use the Similarity slider to adjust grouping behavior:

• Move left → stricter similarity (deduplication)
  
  

• Move right → looser similarity (culling)
  
  

Defining Selection Rules

Each template is driven by rules that determine which image should be picked or rejected within a group.

Common rules include:

• File type (e.g. prioritize RAW over JPEG)
  
  

• Image size / resolution
  
  

• Rating
  
  

• Face quality (for portraits)
  
  

• Aesthetic score (for general culling)
  
  

You can:

• Enable or disable rules
  
  

• Change the order of priority
  
  

• Apply rules automatically or manually
  
  

Different templates emphasize different criteria:

• Deduplication typically prioritizes file type, size, and rating
  
  

• Portrait culling prioritizes face quality
  
  

• Collection culling prioritizes aesthetic score
  
  

Understanding Clusters

After computation, Peakto creates clusters:

• Each cluster contains images considered similar based on the selected similarity level
  
  

• Images without duplicates or similar counterparts are excluded from this view
  
  

Clusters are the foundation of the culling and deduplication workflow.

Picking and Rejecting Images

Within each cluster, you can:

• Pick one or multiple images
  
  

• Reject unwanted images
  
  

Each cluster displays:

• A local summary of picks and rejects
  
  

• A global summary at the top showing totals across all clusters
  
  

Selections can be made:

• Manually, image by image
  
  

• Automatically, by applying rules to all clusters
  

Comparing Images

To review images more closely:

1. Select a cluster
   
   

2. Click Compare
   
   

3. View images side by side (A/B comparison)
   
   

4. Zoom in to inspect details (depending on image availability)
   
   

If original files are online, higher-resolution zoom is available.

Portrait Culling Example

When running portrait culling:

• Images are grouped by similarity
  
  

• Face quality becomes the primary rule
  
  

• You can refine similarity and re-review clusters at any time
