Find and delete duplicate pictures

Duplicate photos are images that have an equal file type, size, and content. They may have titles that are different or the same. These files can be stored in one folder or scattered throughout your Mac’s disk space. Consequently, finding and removing duplicate photo files this way can be time-consuming and frustrating. A much simpler and efficient option is to use the Duplicate File Finder application. This duplicate photo finder app automatically scans your Mac and detects identical pictures in just a few minutes.

To delete duplicate photos from your Mac via Duplicate File Finder, complete the following steps:

  1. Launch the Duplicate File Finder app.
  2. Click on the Scan Home Folder to immediately search duplicate pictures on your disk. To select a particular folder, click on the Add button or drag and drop it to the app’s window and click on the Scan button.

Find Similar images

Similar pictures have the same type, nearly-identical content, and more or less the same size but differ slightly in appearance. It’s most common to find similar pictures when we take a series of photos. These photos with nearly-identical content are easily-noticeable when looking at your photo album. We often leave all the photos from the series, with hopes of returning to them later to delete unnecessary pics. However, these extra images consume limited storage space on your disk.

Using Duplicate File Finder, you can find similar photos and remove them from your Mac. For this, take the following steps:

  1. Launch the Duplicate File Finder app.
  2. Add the folder where you want to detect similar photos and click on the Scan button to start the similar image search.
  3. Then within the scan results window, click on the Similar Photos button.
