These days, instead of wondering where to store pictures and photos, there’s a new question – what to do with the many photos you’ve stored.

It’s not unusual for us to simply ignore the steady accumulation of unnecessary and repetitive files. That is, until the moment this dreaded message appears: “There is not enough storage space.” But, before you go out and buy a new hard drive, there’s a better option – to find and clean up the duplicate files. For this task, you can use a free utility from Nektony called Duplicate File Finder for Mac which allows you to find duplicate images and any other duplicate files in less than a minute.

Our duplicate picture finder provides the best features to quickly delete duplicate photos from your Mac or from an external drive:

  1. Fast scanning algorithm. It takes less than a minute to find duplicate pictures on a modern system disk.
  2. Complete control of the duplicate removal process. Preview the images found directly in the app, and quickly select unneeded copies.
  3. Flexible scan settings. Specify duplicate picture extensions to scan (jpg, png, tiff, etc.) and quickly get the results of all copies of photos detected, without being distracted by other types of files.
  4. Auto Select option. Using this setting, you can minimize the number of steps to select duplicates in bulk and free up disk space.
  5. Multiple file types. Find duplicate images of any type. The most commonly used extensions include .jpeg, .jpg, .gif, .png, .ico, and others. The specific image extensions created by amateur and professional applications include .psd, .pxm, .cdr, .tiff and others.
  6. Restore Removed Duplicates feature. This option allows you to recover accidentally deleted files.

Duplicate photos vs. similar photos

You may have images that are absolutely identical, for example, copies and images that look alike but are not duplicates.

Only files that have an identical type, size, and binary content are real duplicates.
However, some pictures, which at first glance look the same but in closer view are slightly different, are just similar pictures.

Duplicate File Finder also finds such similar pictures, and you can view them in the Similar Photos tab. In this section, you will see images that can be of the same type and almost the same size, but have different content.

In addition to this, you can find similar photos on your iPhone using the free Phone Cleaner app. Phone Cleaner will help you clear your iPhone of unneeded pictures so that you only transfer unique photos to your Mac.

How to find similar images on a Mac

  1. Launch the Duplicate Finder app.
  2. Choose folders in which you want to find similar photos.
  3. Click the Scan button.
