Duplicate Cleaner Pro Overview

Duplicate Cleaner Pro is the ultimate duplicate photo removal application for professional photo organizers!

Start with Search Criteria and select from many powerful matching options. When duplicate groups are displayed in results, you can set preferences and use filters to determine which photos should be removed. 

I’ve been working with Duplicate Cleaner Pro since early 2021, and due to my efforts, many great new features have been added—features I know pro photo organizers need to make duplicate photo and video removal faster and more accurate. 

Duplicate removal is a critical and time-consuming part of digital photo organizing projects.  Duplicate Cleaner Pro may be complicated, but it’s well worth mastering. 

If you’re a Mac user, you’ll want to get a PC (or install Parallels) after you see the demo I am planning!

PhotoSweeper Overview

PhotoSweeper is the only duplicate removal application that can access photos and videos in Apple Photos libraries. 

It can also access photos in Capture One libraries and Lightroom Classic catalogs. Of course, if photos are stored in folders on an internal or external drive and not in a library or catalog, those folders can be compared too.

PhotoSweeper is definitely the most powerful de-duping application for Mac, and is the overwhelming choice for Mac-based professional photo organizers.  

PhotoSweeper Features

Select Compare and choose to look for either:

  • Duplicates – indentical files.
  • Similar Photos – non-identical duplicates
  • Series of Shots.

Similar Photos can be compared based on their Histograms or Bitmaps (which compares pixels) as well as:

  • Size
  • Aspect ratio
  • Format
  • Match level of filename
  • Match level of image – from partial to exact

Before PhotoSweeper compares the photos in the Libraries or folders selected, you can set rules in Preferences that tell Photo Sweeper which photo or photos in a group of duplicates to Auto Mark for removal.

In Preferences, There are 27 different Rules to choose from, and the rules you choose can be placed in order of priority. Here are a just a few of the rules available:

  • Album – mark the file in an Album or not in an Album
  • Favorite – mark the file that is a Favorite or is not a Favorite
  • Capture Date – Mark by earlier or later Capture Date
  • Keywords – mark the file with Keywords or without Keywords
  • Folder Path – mark based on alphabetical order or length of folder path
