Features and performance

  • Find duplicate photos Using “innovative content-based photo comparison algorithm”, Duplicate Photo Finder can look for and identify duplicate images by content, which ensure accuracy. It supports almost all image formats such as JPG, JPEG, TIFF, PSD, PNG, HEIC and BMP. Additionally, it also does a good job of supporting various RAW image formats. In an update in May 2020, the developer increased such support. There is also a Sector Detail Scan mode, which allows users to select a sector on a photo and check other photos for that particular element.
  • Find similar photos Another great thing about Duplicate Photo Cleaner is that it can also find similar photos. You can use it to locate the edited, rotated or cropped version of the same image. It can also scan for photos and pictures that look alike. By setting the custom level of similarity, you can determine how this duplicate photo finder and remover identify similarities in photos.
  • Performance In our test, we used Duplicate Photo Cleaner and another duplicate finder to scan the same folder. The former found 50.83 MB duplicate images, and the latter found 54.55 MB, with the latter using less time. The scan speed is decent most of the time. However, when it comes to a very large amount of files, it may take hours. In a previous test where we tried to scan a whole hard drive, the scanning process remained 0% after 7 minutes. If that’s also your case, you can try to relaunch the app and perform the scan again.
  • Delete with 1 click Users can use this tool to delete duplicates in a safe manner. It will ask for confirmation when users are deleting files. Selected duplicate files can be moved to Trash or be deleted permanently. There is also an option to move selected files to a folder of your choice.
  • Preview without leaving the app The preview feature built-in to Duplicate Photo Cleaner is very useful. Thanks to it, you can conveniently preview images side by side within the app.
  • Support various apps If you are a Mac user, you may be happy with Duplicate Photo Cleaner’s support for the Photos app. With it, it’s very easy to remove duplicates from Photos or iPhoto library. It also has support for Adobe Lightroom and Corel PaintShop Pro, which can be especially useful to photographers, Webmasters and designers.
  • Interface and ease of use The interface is easy to use and uses big, bold fonts which are easy to read and comfortable to the eye. This duplicate photo finder is customizable. You can exclude specific image formats and folders from scanning, and it can make the scan more efficient. Also, it lets you save scans to CSV and a few other formats for later use.
