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.

To find duplicate photos on your Mac, you can use a free utility from Nektony called Duplicate File Finder which allows you to find duplicate images and any other duplicate files in less than a minute.


What are duplicate photos?

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.

What are 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.
