Duplicate image search and removal

If you want to find and remove duplicate images on your storage drives simply start ImageRanger and choose Tools then Duplicates Removal in the Top Menu.

In the configuration dialog it is possible to select several locations (for example, different storage drives). The software will read all image files in the specified folders. Once a duplicate image is found, the confirmation dialog will pop up where you can choose to delete or ignore a new file. All previously found files are also displayed for your convenience, including the information about the file size, resolution and full path.

To automatically remove duplicate photos, choose Minimize Duplicates in the Batch submenu. The removal of duplicate images is supported in the batch processing mode.

Once the destination and source folders are selected, ImageRanger will search the source folder, including all subfolders, and determine if there are any duplicated images and the unique images are copied into the destination folder.

While the batch operation is running, the number of found duplicates is shown in the progress window.

When the operation is finished, the destination folder will contain only unique images in the same folder structure as they appear in the source location.


How to manually locate duplicate photos


While you are browsing an image folder, ImageRanger will check in the background if a similar image has been already discovered.

As soon as the same image is found, a special number appears on the image icon:

To get the actual location of the image on the drive, right click on the image and select Show in explorer. For each duplicate image, the software will show the location in the dropdown menu.

Note. ImageRanger will try to find duplicated images even if the file meta information, file format or file resolution is different. In the event that two similar images have different file sizes, ImageRanger will skip the image with the smaller file size and leave the image with the bigger file size. This is designed to avoid occasional quality loss from the original files.

For more complicated usage, take a look at the Advanced item inside the Batch menu. In the advanced mode, any batch operation, including Resizing, Removal of EXIF, etc., can be configured to discard duplicate images, effectively clearing space on your drive for the unique image content.
