Lightroom Duplicate Finder

Latest Version: 2.0.7466, Friday, 26-Oct-2018 21:06:18 BST (Changes in this version)

Please note this is no longer compatible with Lightroom 2.

One of the main missing functions within Adobe Lightroom is the ability to locate duplicate images. This plug-in does just that, based on a variety of EXIF data.

There are already utilities which will compare files to see if they're identical, but they don't cope well with Lightroom images. Because Lightroom can write metadata back into the files, identical photos can be different on disk because of something as simple as a 'last edit time' value. They also don't help where one image has been changed, for example scaled, but is still essentially the same image.

By using the EXIF data, this plugin finds all photos which came from the same source; it compares the camera model, serial number, lens, ISO speed etc. It can also filter by keywords and filename to narrow results down further.

The safest way to delete your duplicates!

Once you've identified all the duplicates, using custom matching rules if need be, you can safely and easily choose which to delete. DON'T trust anything that offers to automatically delete all your duplicates, you WILL lose important photos! This plugin is safe. It groups all combinations of duplicates together so that you can choose individually, or do a mass-delete safely, guaranteeing to leave at least one copy of each duplicate set. See here for more information.

Identify and Fix a Damaged Catalog!

Since V2.0.7438

Over time your Lightroom catalog can accumulate damaged records. These usually cause no problems - unless you try to access that photo in Lightroom, when strange things can start to happen. If you're seeing this, you need to try the Duplicate Finder's "Repair Catalog Damage" function.

Since it accesses your entire catalog at once, the Duplicate Finder is - unfortunately - very good at identifying the faulty records in a damaged catalog. It will now quickly and simply identify exactly which records are faulty and isolate them for you, allowing you to easily repair many types of catalog damage by removing and re-importing the affected photos. See over at Learn to Lightroom for more details.


  • Scan the entire catalog, or a selection, or within a selection, for duplicate images.
  • You can choose what EXIF data is used for matching.
  • Results displayed in a Smart Collection, with matched photos grouped together.
