Duplicate Finder

Latest Version: 2.0.5599 (History)

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.


  • 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.
