Find all duplicate photos

A set of duplicate photos is two or more exactly identical photos (regardless of name). Cisdem Duplicate Finder finds duplicate JPG files, HEIC files, PNG files and all other duplicate images, including duplicate raw photos.

This duplicate photo finder uses smart algorithms to compare photos and identify duplicates by content and size, ensuring absolute accuracy and high efficiency. In addition, it offers another scan method, which compares photos by name only.

Also find similar photos

Cisdem Duplicate Finder detects similar photos too, such as a batch of photos taken in burst mode (which look alike or even the same to the naked eye) and similar pictures of the same scene captured from slightly different angles or distances. It groups similar photos into sets for you to easily pick the best shots to keep and delete the redundant ones.

You can decide how strict the identification of similar photos will be. Being strict means only photos that have high similarity will be found. Being looser means more photos will be found, with more difference being allowed.
